Pulse Modulation Flashcards
What is an important factor in pulse-code modulation using time-division multiplex?
Synchronization of transmit and receive clock pulse rates.
In a pulse-width modulation system, what parameter does the modulating signal vary?
Pulse duration.
What is the name of the type of modulation in which the modulating signal varies the duration of the transmitted pulse?
Pulse-width modulation
Which of the following best describes a pulse modulation system?
The peak transmitter power is normally much greater than the average power.
In a pulse-position modulation system, what parameter does the modulating signal vary?
The time at which each pulse occurs.
What is one way that voice is transmitted in a pulse-width modulation system?
A standard pulse is varied in duration by an amount depending on the voice waveform at that instant.
