Abstract: Two methods of FM Signal demodulation, phase shift discrimination and looking up arcsine table, are discussed and verified by using TMS 320C50 DSK. Experimental results show that these methods have a good effect on the demodulation under certain conditions.

Key words: FM, FIR filter, digital demodulation
