Answer #1

Differential phase shifting key, here the phase of signal is sifted with relevance to the previous signal, here no reference is being considered. like if the data bit is low then it is not being reveresed and continue as it and if the data bit is high than it get reversed.DPSK nodulator is used to encode the two signal that are the carrier and modulator with 180 degree angle and with no reference phase signal and the transmitted can itslef be considered as the reference. DPSK demodulator is used to decode the signal.

The message m(t) = 5 cos(2?1000t) is frequency-modulated to 90MHz, with kf=2000?. Determine the frequency deviation and deviation ratio of the FM signal. Also estimate the bandwidth of the FM signal. Suppose now you are provided with a crystal oscillatorat 90MHz, an analog multiplier, and a second-order loop filter, and a VCO. Explain by drawing a block diagram how the FM signal can be demodulated using these components. Specify the minimum required operation range of the VCO.
