(see Fig. 1A) in which the carrier wave is defined into a plurality of blocks and all the cycles but one at least within each block are subjected to amplitude modulation, and a demodulator (see Fig. 2A) for reproducing the digital data from a recorded or transmitted modulated signal ...
A carrier wave is frequency modulated(FM)using a sinusoidal of frequencyfm=3KHZ,it is found that the carrier component of FM signal is reduced to zero for the second time whenAm=2volts. What is the frequency sensitivity of the...
