WebTo explain the concept and purpose of adaptive filters. Demodulation is the process of restoring the data bits back from a digitally modulated signal. Last week we discussed a simple digital communication scheme called Binary Phase Shift Keying (BPSK). In BPSK, we take a stream of bits and map these bits to a stream of symbols with value -1 or +1. WebNov 1, 2015 · The proposed FM modulator and demodulator has been implemented and tested using XC2VP30-7ff896 FPGA as a target device and can operate at a maximum frequency of 334.5 MHz and 131 MHz involving ...
