The study developed and evaluated the performance of an improved algorithm to demodulate sampled data frequency modulation (FM) signals in typical field programmable gate array (FPGA) - based software defined radios (SDR). An algorithm, based on the modification of a standard differentiate-divide FM demodulator was developed. The hardware resources requirement and the input noise suppression ability of the developed algorithm were investigated. The demodulator developed requires a quarter of the hardware resources needed by conventional differentiate-divide FM demodulators. The output signal to noise ratio (SNR) of the developed demodulator is lower than that of the standard differentiate divide-demodulator when the input carrier to noise ratio (CNR) is less than 45 decibels. The SNR plot of the developed demodulator is more linear, compared to that of the original differentiate-divide demodulator. This implies that the developed demodulator can be implemented using smaller sized FPGAs, thus reducing cost and the power dissipated. The small silicon area occupied by the demodulator gives room for instantiation of more demodulators and other signal processing units on the same FPGA chip
