Plot the output as a function of input voltage. Enter sufficient number of readings in Table 8.2. Does the output remain constant as the magnitude of the input is increased? Beyond what value of the input voltage does the gain begin to stabilize? We have included sample output waveform for the AGC circuit in Figure 8.3.
