Matlab produce a frequency for 1 hz, power for 1 cosine source, a carrier frequency for 10 hz and draw the:
1. The DSB modulation signal and power spectral density
2. Will be modulated signal demodulation, in the time domain waveform and the demodulation of the original signal are compared
3. A = 2 AM modulation signal and power spectral density
4. SSB modulation signal and power spectral density
5. In the channel of each join after bandpass filter after the narrow band gaussian white noise, power is 0.1, each signal demodulation, and draw the demodulation of waveform.
