An arbitrary waveform generator (AWG) is a specialized electronic test instrument that can create any waveform shape the user ...

Vary the Amplitude In AM modulation, the voltage (amplitude) of the carrier is varied by the incoming signal. In this example, the modulating wave implies an analog signal.

The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point. See ...
