- Problems
- XTRA Credit
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.
