i came to know that FM demodulation can be done through envelope detection. i have implemented the FM demodulation using envelope detection and i was unable to detect the original signal. i have not implemented the limiter circuit for this. i have passed the FM signal directly to the BPF followed by differentiator and envelope detector how to implement the limiter circuit. please help me.

This is followed by a band-pass filter. A high-bandwidth op-amp would work (no feedback) though you could obtain a specialist IC for the purpose.
