Synonyms of Modulation
Example sentences (20)
In this modulation narrowband FM is generated leading to wideband FM later and hence the modulation is known as Indirect FM modulation.
It can also be viewed as a change of the frequency of the carrier signal, and phase modulation can thus be considered a special case of FM in which the carrier frequency modulation is given by the time derivative of the phase modulation.
Modulation index As in other modulation systems,the modulation index indicates by how much the modulated variable varies around its unmodulated level.
Modulation index The AM modulation index is a measure based on the ratio of the modulation excursions of the RF signal to the level of the unmodulated carrier.
Adaptive delta modulation Adaptive delta modulation (ADM) was first published by Dr. John E. Abate (AT&T Bell Laboratories Fellow) in his doctorial thesis at NJ Institute Of Technology in 1968.
A delta modulation (DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance.
Amplitude modulation results when the carrier c(t) is multiplied by the positive quantity (1+m(t)): : In this simple case M is identical to the modulation index, discussed below.
Another feature to make LS AAS element-specific is modulation of the primary radiation and the use of a selective amplifier that is tuned to the same modulation frequency, as already postulated by Alan Walsh.
Flywheel effect is used in class C modulation where efficiency of modulation can be achieved as high as 90%.
For a sine wave modulation, the modulation index is seen to be the ratio of the peak frequency deviation of the carrier wave to the frequency of the modulating sine wave.
Frequency modulation main Another form of distance measuring radar is based on frequency modulation.
Immune response modulation Cytokine modulation An effective vaccine must induce an appropriate immune response for a given pathogen.
In EGPRS/EDGE, the Modulation and Coding Schemes MCS-1 to MCS-9 take the place of the Coding Schemes of GPRS, and additionally specify which modulation scheme is used, GMSK or 8PSK.
In radio transmission, an advantage of frequency modulation is that it has a larger signal-to-noise ratio and therefore rejects radio frequency interference better than an equal power amplitude modulation (AM) signal.
It is thus defined as: : where and are the modulation amplitude and carrier amplitude, respectively; the modulation amplitude is the peak (positive or negative) change in the RF amplitude from its unmodulated value.
Jaxon modulation is a modulation system for placing information on a bitstream generated by a finite generator.
Mathematically both phase and frequency modulation can be considered a special case of quadrature amplitude modulation (QAM).
Mechanically induced modulation is an optical signal modulation induced by mechanical means.
Modulation Immunity to fading and inter-symbol interference (caused by multipath propagation) is achieved without equalization by means of the OFDM and DQPSK modulation techniques.
Modulation main Modulation, in general electronics, means the altering of signal strength.
