In _______________,the pulse amplitude is made proportional to the amplitude of the modulating signal.
A)pulse-width modulation (PWM)
B)pulse-amplitude modulation (PAM)
C)pulse-position modulation (PPM)
D)pulse-code modulation (PCM)

Question

Quizplus · Accepted Answer

Pulse-amplitude modulation (PAM) is a modulation technique in which the amplitude of the pulse signal is varied in accordance with the amplitude of the modulating signal. This ensures that the information or signal transmitted is properly conveyed to the receiver end without any distortions. The other options, PWM, PPM, and PCM, have different mechanisms of modulation and are not specifically based on the amplitude of the modulating signal.
