(a) Try to demodulate an FM signal on the edge of a lowpass filter
(b) Try to demodulate an FM signal with the same cutoff frequency as (a) on the edge of a highpass filter. How do the results differ?
(c) Repeat (a) and (b) with a realistic source signal (filtered noise).
(d) Design a phase detector according to Illustration 179.
(e) Try to replicate the experiment carried out in Illustration 180. (f) On your own design a PLL as in Illustration 181 and try to set the control voltage for the VCO in such a way that the PLL works.
