Abstract :
A very simple method to demodulate the digital frequency modulated (FM) signal is presented in this paper. A unit delay operator, multiplier, lowpass filter, arccosine function, and adder are employed. The proposed method is easily adjusted and controlled. The computer simulations are conducted to demonstrate the performance of the proposed technique.
