In pulse position modulation ________.
A) the position of a pulse relative to a reference signal varies based upon its amplitude relative to the amplitude of the modulating signal
B) the position of a pulse relative to a reference signal varies based upon the value of the modulating signal
C) the amplitude of a pulse varies based upon its position relative to the zero-crossing of the modulating signal
D) the frequency of a pulse waveform varies based upon the position of the zero-crossing of the modulating signal relative to a reference signal
Question 2
An intersective method of pulse width modulation ________.
A) compares the value of a reference sine wave intersecting the modulating signal to determine the pulse width
B) compares the value of a reference dc voltage intersecting the modulating signal to determine the pulse width
C) compares the value of a pulse waveform intersecting the modulating signal to determine the pulse width
D) compares the value of a sawtooth waveform intersecting the modulating signal to determine the pulse width
