8. Turn the potentiometer clockwise to the maximum. Adjust the
UP button on the Baseband module to adjust the frequency of
modulating signal. Do you see any change in the AM wave
spectrum? Compare the experiment results with that of the
original baseband frequency of 100kHz and record it to Table 5-
5.
