This is single-sideband modulation, widely used in amateur radio and other communications applications.

Nevertheless, even though switching amplifiers are completely unsuitable for normal QAM constellations, often the QAM modulation principle are used to drive switching amplifiers with these FM and other waveforms, and sometimes QAM demodulators are used to receive the signals put out by these switching amplifiers.

As with other modulation indices, this quantity indicates by how much the modulated variable varies around its unmodulated level.

* Modulation for a list of other modulation techniques

A wide variety of other algorithms were tried at the time, mostly variants on delta modulation, but after careful consideration, the A-law / μ-law algorithms were chosen by the designers of the early digital telephony systems.

FM modulation of the color information allows SECAM to be completely free of the dot crawl problem commonly encountered with the other analog standards.

The earlier systems System A & the 819-line systems were the only other systems to use positive video modulation.

Single-sideband has the mathematical form of quadrature amplitude modulation in the special case where one of the baseband waveforms is derived from the other, instead of being independent messages:

* Modulation for other examples of modulation techniques

Continuous wave ( Morse code ) and single sideband signals require a product detector using a so-called beat frequency oscillator, and there are other techniques used for different types of modulation.

Soon, advanced multimode electronic interfaces such as the AEA PK-232 were developed, which could send and receive not only packet, but various other modulation types including Baudot.

Apart from vocoders, several other methods of producing variations on this effect include: the Sonovox, Talk box, and Auto-Tune, linear prediction vocoders, speech synthesis, ring modulation and comb filter.

The putamen also plays a role in modulation of other neurotransmitters.

The striatum is best known for its role in the planning and modulation of movement pathways but is also potentially involved in a variety of other cognitive processes involving executive function, such as working memory.

AFSK is not always used for high-speed data communications, since it is far less efficient in both power and bandwidth than most other modulation modes.

In FM broadcasting and other analog radio media, multiplexing is a term commonly given to the process of adding subcarriers to the audio signal before it enters the transmitter, where modulation occurs.

LED drivers based on the PAM technique offer improved energy efficiency over systems based upon other common driver modulation techniques such as pulse-width modulation ( PWM ) as the forward current passing through an LED is relative to the intensity of the light output and the LED efficiency increases as the forward current is reduced.

Many other types of modulation are used.

: Many other types of modulation are also used.

The other method of creating screens — frequency modulation — is used in a process also known as stochastic screening.

On the other hand, for a signal modulated with an angular modulation, we must use an FM ( Frequency Modulation ) demodulator or a PM ( Phase Modulation ) demodulator.

Then, by simply placing a carbon microphone in the transmission line, the strength of the signal could be varied in order to add sounds to the transmission — in other words, amplitude modulation would be used to impress audio on the radio frequency carrier wave.

Positive allosteric modulation ( also known as allosteric activation ) occurs when the binding of one ligand enhances the attraction between substrate molecules and other binding sites.

The foregoing have been methods of charting prices, but now let us look at some of the other indices that are customarily charted, and which are looked to for their forecasting abilities.

Taking advantage of this feature, some languages ( like FORTRAN 77 ) specify that array indices begin at 1, as in mathematical tradition ; while other languages ( like Fortran 90, Pascal and Algol ) let the user choose the minimum value for each index.

This and other similar indices do not define a free market, but measure the degree to which a modern economy is free, meaning in most cases free of state intervention.

These indices are used for estimation of other engineering properties and for soil classification.

However, systematic evaluations have found them to align closely with freedom indices from other sources.

While PageMaker's pasteboard metaphor closely simulated the process of creating layouts manually, Ventura Publisher automated the layout process through its use of tags / style sheets and automatically generated indices and other body matter.

Norway is among the most expensive countries in the world, as reflected in the Big Mac Index and other indices.

* Linear data structures: Locality often occurs because code contains loops that tend to reference arrays or other data structures by indices.

These are all general issues of indexing ; as with other price indices there is no way to reduce complexity to a single number that is equally satisfying for all purposes.

In addition to the Conference Board's CCI, other survey-based indices attempt to track consumer confidence in the U. S .:

The other indices are

As with other cities in the eastern U. S., periods of high humidity can raise heat indices to near 110.

* FTSE 100 Index and other stock market indices

In 1 December 2003, the index's weighting system switched from being dependent on total market capitalisation to free float market cap only, in line with other leading indices.

In linear algebra and theoretical physics, the adjective antisymmetric ( or skew-symmetric ) is used for matrices, tensors, and other objects that change sign if an appropriate operation ( usually the exchange of two indices, which becomes the transposition of the matrix ) is performed.

In components, it is expressed as a sum of products of scalar components of the tensor ( s ) caused by applying the summation convention to a pair of dummy indices which are bound to each other in an expression.

The contraction of a single mixed tensor occurs when a pair of literal indices ( one a subscript, the other a superscript ) of the tensor are set equal to each other and summed over.

Notationally, these tensors differ from each other by the covariance / contravariance of their indices.

* Two-point tensor, which generalizes this notion to tensors that have indices not just in the primal and dual space but in other vector spaces ( such as other tangent spaces on the same manifold ).

Indices for futures include well-established indices such as S & P, FTSE, DAX, CAC40 and other G12 country indices.
