Using the Matlab
Communications Toolbox, design and develop a demo to illustrate AM,
DSB-SC and SSB modulation and demodulation for an arbitrary message
signal.
The function should allow input of the carrier frequency and provide
displays
for the message, modulated and demodulated signals in the time and
frequency
domains. XTRA XTRA Credit if you also provide a facilility for
adding
Gaussian noise to the modulated signal. Hint: You will need the
functions >>amod and >>ademod for
designing this demo.
