In practice, digital computation is often used to simulate natural processes ( for example, evolutionary computation ), including those that are more naturally described by analog models of computation ( for example, artificial neural network ).

The first of these two methods is more commonly encountered in practice because many industrial systems have many continuous systems components, including mechanical, fluid, biological and analog electrical components, with a few digital controllers.

In practice, almost-perfect copies can typically be made by tapping into the analog output of a player ( e. g. the speaker output or headphone jacks ) and, once redigitized into an unprotected form, duplicated indefinitely.

Less formally than the theoretical distinctions mentioned above, two main types of signals encountered in practice are analog and digital.

The Shou practice mainly two forms of religion, " The Path of Enlightenment " ( analog for Confucianism and to an extent, Theravada Buddhism ) and " The Way " ( analog for Daoism ).

Due to the need for filtering out ultrasonic frequencies resulting from the conversion to an analog signal, in practice slightly higher sample rates are used: 44. 1kHz ( CD audio ) or 48kHz ( DVD ).

In practice, companders are designed to operate according to relatively simple dynamic range compressor functions that are designed to be suitable for implementation using simple analog electronic circuits.

The same practice was true of all analog channel 6 television stations in North America.

There is no specific requirement for any particular transmission mode on 900, 1. 9, 2. 4, and 5. 8, but in practice, virtually all newer 900 MHz phones are inexpensive analog models with digital features such as DSSS and FHSS generally available only on the higher frequencies.

He further stated that the digital pad and touchscreen's virtual analog control were " tricky " and required practice.

It is common practice to broadcast an older, discontinued format on HD2 channels ; for example, with the recent disappearance of the smooth jazz format from the analog radio dial in many markets, stations such as WDZH in Detroit, Michigan ( formerly WVMV ), WQCD in New York City, WPGB in Pittsburgh, Pennsylvania and WNWV in Cleveland, Ohio program smooth jazz on their HD2 or HD3 bands.

In addition to the controversial practice of converting the HD Radio-only secondary channels of a primary station into analog FM in areas where the primary station's signal can already readily be received, translators can also be used in a more traditional manner to extend the range of the full content of the primary station, including the unmodified main signal and any HD radio sub-channels, in areas where the station has poor coverage or reception, as is done at K202BD in Manti, Utah, which rebroadcasts both the analog and digital signals of KUER from Salt Lake City.

Participants made a series of recommendations for improving the practice of analog audio transfer for archiving.

( In order to keep the analog / digital signals in sync, it is standard practice for Hybrid Digital Radio to delay all content by a few seconds.

What makes ciphony difficult in practice is a need to send the encrypted signal over the same voiceband communication circuits used to transmit unencrypted voice, e. g. analog telephone lines or mobile radios.

In practice the law had little effect, but it did signal political support for abolishing slavery in the Confederacy

In practice, 802. 11b typically has a higher range at low speeds ( 802. 11b will reduce speed to 5 Mbit / s or even 1 Mbit / s at low signal strengths ).

Without this capacity, which is often the case in practice, to produce a representation with lower resolution or lower fidelity than a given one, one needs to start with the original source signal and encode, or start with a compressed representation and then decompress and re-encode it ( transcoding ), though the latter tends to cause digital generation loss.

It cannot be realized in practice since it implies that each sample contributes to the reconstructed signal at almost all time points, requiring summing an infinite number of terms.

* Furthermore, in practice, a signal can never be perfectly bandlimited, since ideal " brick-wall " filters cannot be realized.

In practice, the terms STS-1 and OC-1 are sometimes used interchangeably, though the OC designation refers to the signal in its optical form.

In practice, the useful resolution of a converter is limited by the best signal-to-noise ratio ( SNR ) that can be achieved for a digitized signal.

Any modulated signal will have an infinite number of sidebands and hence an infinite bandwidth but in practice all significant sideband energy ( 98 % or more ) is concentrated within the bandwidth defined by Carson's rule.

This practice also ensures that, in case of a fault in the signalling system, an incapacitated signalman, or the unexpected entry of a train, that a train will never be shown an erroneous " clear " signal.

Although overmodulation is sometimes considered permissible, it should not occur in practice ; a distorted waveform envelope will result in a distorted output signal of the receiving medium.

Later on when Foucault went to Iran “ to be there at the birth of a new form of ideas ,” he wrote that the new “ Muslim ” style of politics could signal the beginning of a new form of “ political spirituality ,” not just for the Middle East, but also for Europe, which had adopted the practice of secular politics ever since the French Revolution.

A common means by which a bottom or submissive can signal to a top or dominant partner that their limits are being approached, pushed, or even crossed is the use of safewords ; Extreme forms of submission or the practice of edgeplay can remove the safeword option from the bottom or submissive, although, this somewhat risky situation is entered into with the consent of the bottom or submissive.

* Impedance matching, the electronics design practice of setting the input impedance of an electrical load equal to the fixed output impedance of the signal source to which it is ultimately connected

In practice, the propagation characteristics of these radio waves vary substantially depending on the exact frequency and the strength of the transmitted signal ( a function of both the transmitter and the antenna characteristics ).

* Transponder – In practice, the signal inputs and outputs will not be electrical but optical instead ( typically at 1550 nm ).

* Chirplet transform, 1991: Mann was the first to propose and reduce to practice a signal representation based on a family of chirp signals, each associated with a coefficient, in a generalization of the wavelet transform that is now referred to as the chirplet transform.

An in-ear microphone, while involving an additional distorting step by converting the electrical signal to sound and back again, in practice gives better-matched volume.

) Another interesting practice seen at least in Ontario is that cars wishing to turn left that arrived after the left turn signal ended can do so during the yellow phase, as long as there is enough time to make a safe turn.

In software engineering practice, they are often called wait and signal, acquire and release ( which the standard Java library uses ), or pend and post.

The practice of smoking marijuana was bought to Brazil from its African slaves, and with the eugenic positivist intellectual and political status quo of the Western civilization in the early 20th century, its use was deemed as a signal of decadence by its stigmatized use as a recreational drug of the poor, the rural people and the Afro-Brazilian.

Information was then separately encoded and folded into the signal as a high-frequency modification to produce a composite video signal – on a black and white television this extra information would be seen as a slight randomization of the image intensity, but the limited resolution of existing sets made this invisible in practice.

The ideal impulse response can be chosen independently of the ideal frequency function and is in practice used to limit the effective width and to remove ringing effects of the resulting filter in the signal domain.

As a word of caution, we should be aware that in actual practice no message is purely one of the four types, question, command, statement, or exclamation.

It will readily be seen that in this suggested network ( not materially different from some of the networks in vogue today ) greater emphasis on monitoring is implied than is usually put into practice.

The discrepancy between what we commonly profess and what we practice or tolerate is great, and it does not escape the notice of others.

What is more, the legends have become so sacrosanct that the very habit of self-examination or self-criticism smells of low treason, and men who practice it are defeatists and unpatriotic scoundrels.

My reply is that I associate myself with all those who affirm that Gentile-Jewish relations should contribute to the theory and practice of human dignity.

The principle is commendable but we suspect that in the practice somebody is going to get gulled.

and, though he repeated, over and over again, the spectacular figures of industrial and agricultural production in 1980, the `` ordinary '' people in Russia are still a little uncertain as to how `` communism '' is really going to work in practice, especially in respect of food.

If this practice should take root and spread, the man who submits a manuscript to a publisher will find himself reviewed before he is accepted and publication will become a sort of post-mortem formality.

It should be enough to say that the practice of the state buying automobiles is at least forty years old.

The location of the latter now is determined for tax purposes at the time of registration, and it is now accepted practice to consider a motor vehicle as being situated where it is garaged.

This condition will undoubtedly continue until such time as a state uniform system of evaluation is established, or through mutual agreement of the local assessing officials for a method of standard assessment practice to be adopted.

To summarize, it may be said that there is no one prevailing practice in Rhode Island with respect to the taxation of movable property, that assessors would like to see an improvement, and of those who have an opinion, that assessment by the town of location is preferred on the basis of their present knowledge.

The One Leg Lunge is a split and all lifters practice this in their regular workouts.

A second and also good practice is to shear off the tops, leaving an inch high stub with just a leaf or two on each branch.

The Targo is a good outfit for fun shooting or for economic wing-shooting practice, but it's tougher than it looks to run up a score on the clay birds.

Acreage in excess of the minimum is good practice as recreation areas are never too large for the future and it is often more economical to operate one large area than several small ones.

To practice new procedures under guided supervision and with constant feedback is the fourth step.

It is the classroom teacher, however, who has daily contacts with pupils, and who is in a unique position to put sound psychological principles into practice.
