How do you demodulate FM waves?

A simple and effective FM demodulation technique involves a high-pass filter (for FM-to-AM conversion) followed by an AM demodulator. A high-pass-filter-based FM demodulator is preceded by a limiter to prevent amplitude variations from contributing error to the demodulated signal.

What are the two methods to demodulation?

Based on this nonlinearity, the demodulation methods can be broadly classified as methods using rectification (non-synchronous detection) and methods using mixing with a reference oscillator signal (synchronous detection).

What are demodulation techniques?

Demodulation is done using a product detector and with a local beat frequency oscillator or a carrier injection oscillator. The incoming signal cannot be synchronized by the local oscillator carrier and should be of the basic form.
