The purpose of the exercise is to demonstrate the properties of SSB modulation. Develop a computer program to generate both upper-sideband and lower-sideband SSB signals and display both the time-domain signals and the amplitude spectra of these signals. Assume the message signal
Select both fm and fc so that both the time and frequency axes can be easily calibrated. Plot the envelope of the SSB signals, and show that both the upper-sideband and the lower-sideband SSB signals have the same envelope. Use the FFT algorithm to generate the amplitude spectrum for both the upper-sideband and the lower sideband SSB signal.
a. Given a circuit with a VCVS (A=1000) in series with a 100K ohm resistor, convert this circuit to a VCCS in parallel with a resistor R. b. Connect both circuits to a 25K ohm load resistor and show they produce the same behavior in the load resis..
