Development of a Sampled Data Frequency Modulation (FM) Demodulator

This book explores the development of an improved algorithm for the demodulation of sampled-data frequency modulation (FM) signals. The developed algorithm, which is a modified form of the standard differentiate-divide FM demodulator was modelled in MATLAB/SIMULINK environment. Its silicon area requirement on an FPGA chip was investigated using Quartus software. Results show that the developed algorithm has a higher time/silicon area ratio compared to the standard differentiate-divide demodulator.
