What does a demodulator do?

A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave. There are many types of modulation so there are many types of demodulators.

How do you demodulate amplitude modulation?

This ASK modulated position signal is demodulated by mixing the signal with a pure sine wave carrier at the frequency of the underlying oscillation, and then low pass filtering it to obtain position envelope.

How do you demodulate an over modulated signal?

In order to demodulate a double-modulated signal such as , at least two demodulators are necessary. Using the tandem technique, the in-phase or X-component of demodulated signal at the carrier frequency is internally routed to the second demodulator at sideband frequency.
