In pulse position modulation _________.
A) the position of a pulse relative to a reference signal varies based upon the value of the modulating signal
B) the position of a pulse relative to a reference signal varies based upon its amplitude relative to the amplitude of the modulating signal
C) the frequency of a pulse waveform varies based upon the position of the zero- crossing of the modulating signal relative to a reference signal
D) the amplitude of a pulse varies based upon its position relative to the zero- crossing of the modulating signal

Question

Quizplus · Accepted Answer

In pulse position modulation (PPM), the position of a pulse within a given time frame varies according to the amplitude of the modulating signal, relative to a reference signal. This means that the timing of the pulse's occurrence (its position) changes based on the value of the modulating signal, not its amplitude, frequency, or any zero-crossings.
