The sampling rate should be at least twice the bandwidth of the signal, in order to fully reconstruct the signal..

Standard Amplitude Modulation (AM). nalhareqi-2013. 2. In the DSP-SC demodulation, a receiver must generate a local carrier in frequency and phase synchronism with the carrier used for modulation.. In coherent phase shift keying different phase modulation schemes will be covered i.e. binary PSK, quadrature phase shift keying and M-. ary. PSK . Binary PSK will be studied in the next slides. 1.
