Abstract
By analyzing the mathematical models of an FM signal, three demodulation algorithms are presented, in this paper, which can be easily implemented with software. All the demodulation steps of FM signals can be equivalent to simple FIR filters, so complex computation can be greatly reduced. All the methods have been simulated correctly.
