Yamaha's engineers began adapting Chowning's algorithm for use in a commercial digital synthesizer, adding improvements such as the " key scaling " method to avoid the introduction of distortion that normally occurred in analog systems during frequency modulation, though it would take several years before Yamaha release their FM digital synthesizers.

The method is called low-frequency heating ( LFH ) since the current is injected at a much lower frequency than the nominal of the grid, which is normally 50 or 60 Hz.

In the first case, the condition of bandlimitation of the sampled signal can be accomplished by assuming a model of the signal which can be analysed in terms of the frequency components it contains ; for example, sounds that are made by a speaking human normally contain very small frequency components at or above 10 kHz and it is then sufficient to sample such an audio signal with a sampling frequency of at least 20 kHz.

With a radio operator initiating a call, the process normally takes a few minutes for the ALE to pick an HF frequency that is optimum for both sides of the communication link.

Crystal manufacturers normally cut and trim their crystals to have a specified resonance frequency with a known ' load ' capacitance added to the crystal.

The FOT is normally just below the value of the maximum usable frequency ( MUF ).

Very high frequency waves and higher normally travel through the ionosphere wherefore communication via skywave is exceptional.

RF and microwave signal generators normally have similar features and capabilities, but are differentiated by frequency range.

Piezoelectric speakers have several advantages over conventional loudspeakers: they are resistant to overloads that would normally destroy most high frequency drivers, and they can be used without a crossover due to their electrical properties.

This frequency varies normally but the range is 45 – 50 kHz for the cardiac arrest or for the heart failure.

Transponders are a combination of receiver and transmitter who's operation is automated-upon reception of a particular signal, normally a pulse on a particular frequency, the transponder sends out a pulse in response, typically delayed by some very short time.

In use, the RDF operator would first tune the receiver to the correct frequency, then manually turn the loop, either listening or watching an S meter to determine the direction of the null ( the direction at which a given signal is weakest ) of a long wave ( LW ) or medium wave ( AM ) broadcast beacon or station ( listening for the null is easier than listening for a peak signal, and normally produces a more accurate result ).

A WAP normally connects directly to a wired Ethernet connection and the WAP then provides wireless connections using radio frequency links for other devices to utilize that wired connection.

In SI units, angular frequency is normally presented in radians per second, even when it does not express a rotational value.

There are good used cars (" cherries ") and defective used cars (" lemons "), normally as a consequence of several not-always-traceable variables such as the owner's driving style, quality and frequency of maintenance and accident history.

At least one mathematical model has been developed where both codon-usage and tRNA-expression co-evolve in feedback fashion ( i. e., codons already present in high frequencies drive up the expression of their corresponding tRNAs, and tRNAs normally expressed at high levels drive up the frequency of their corresponding codons ), however this model does not seem to yet have experimental confirmation.

The clock rate of a CPU is normally determined by the frequency of an oscillator crystal.

N sets the NCO frequency resolution and is normally much larger than the number of bits defining the memory space of the PAC look-up table.

The amount of tuning in this manner is not large and is normally used for frequency modulation when transmitting.

Unlike DVDs, which carry Dolby Digital audio in digital form, Laserdiscs store Dolby Digital in a frequency modulated form within a track normally used for analog audio.

A spurious emission is any radio frequency not deliberately created or transmitted, especially in a device which normally does create other frequencies.

The music playback equipment used motors that got their speed timing from the frequency of the powerline, normally 60Hz.

Flicker noise is electronic noise with a 1 / ƒ frequency spectrum ; as f increases, the noise decreases.

* Pressure – increasing the pressure decreases the volume between molecules and therefore increases the frequency of collisions between the molecules.

As frequency increases into the visible range, photons of EMR have enough energy to change the bond structure of some individual molecules.

As frequency increases beyond visible into the ultraviolet, photons now carry enough energy ( about three electron volts or more ) to excite certain doubly bonded molecules into permanent chemical rearrangement.

With a tone-modulated FM wave, if the modulation frequency is held constant and the modulation index is increased, the ( non-negligible ) bandwidth of the FM signal increases but the spacing between spectra remains the same ; some spectral components decrease in strength as others increase.

If the frequency deviation is held constant and the modulation frequency increased, the spacing between spectra increases.

The efficiency of a transformer may decrease as the frequency increases due to eddy currents in the core material and skin effect on the windings.

The frequency of hypoglycemia increases with increasing effort to achieve normal blood glucoses with any insulin regimen.

The first has to do with positive affect ; an overall positive mood increases the frequency of helping behavior.

This theory stems from a history of numerous studies indicating that positive mood increases the frequency of helping and prosocial behaviors.

In genetics, a mutagen ( Latin, literally origin of change ) is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level.

Increasing the frequency of the incident beam, keeping the number of incident photons fixed ( this would result in a proportionate increase in energy ) increases the maximum kinetic energy of the photoelectrons emitted.

Increase in intensity of incident beam ( keeping the frequency fixed ) increases the magnitude of the photoelectric current, though stopping voltage remains the same.

Einstein's work predicted that the energy of individual ejected electrons increases linearly with the frequency of the light.

By 1905 it was known that the energy of photoelectrons increases with increasing frequency of incident light and is independent of the intensity of the light.

Another reason for heterodyne processing is that for fixed fractional bandwidth, the instantaneous bandwidth increases linearly in frequency.

Its wavelength increases or decreases but its frequency remains constant.

Wavelength increases up towards the red and beyond ( frequency decreases ).

Rainfall is mainly orographic and increases in amount and frequency with the altitude.

The left shift to a lower resonant frequency increases the volume of some low frequency sounds due to the longer waves propagated by the increased excursion of the hard diaphragm member suspended in the concentric accountic surround.

The image frequency is 2f < small >< sub > IF </ sub ></ small > higher ( or lower ) than f < small >< sub > d </ sub ></ small >, so employing a higher IF frequency f < small >< sub > IF </ sub ></ small > increases the receiver's image rejection without requiring additional selectivity in the RF stage.
