Limiter circuits are normally amplifiers with high gain leading to
saturation. 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.

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.
