Question

1. an am modulated output signal of a function generator is developed by

a changing the amplitude of the output signal
b changing the frequency of the output signal
c changing the shape of the triangle wave
d changing the shape of the square wave

Explanation:

AM (Amplitude - Modulation) is a modulation technique where the amplitude of the carrier wave is varied in accordance with the message signal. So, an AM - modulated output signal of a function generator is developed by changing the amplitude of the output signal.

Answer:

A. changing the amplitude of the output signal
