Conclusion

4. Draw a table to record the time domain waveform of the AM

wave that is measured by the oscilloscope.

Question

1.

For FM waves, if we keep the modulation signal amplitude
constant and double the modulation signal frequency, how will
the frequency deviation and bandwidth change in the
modulated signal?

2.

Calculate the FM index of the modulation circuit through the
measured data obtained from the spectrum analyzer.
