Answer 3

pulse width modulation

Question 4

Which of the following best describes a pulse modification system?

Answer 4

the peak transmitter power is normally much greater than the average power

Question 5

In a pulse position modulation system, what parameter does the modulating signal vary?

Answer 5

is the time which each pulse occurs

Question 6

What is one way that voice is transmitted in a pulse width modulation system?

Answer 6

a standard pulse is varied in duration by an amount depending on the voice waveform at that instant
