Everything about Demodulation
Process of extracting the original information-bearing signal from a carrier wave
Demodulation is the process of extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit that is used to recover the information content from the modulated carrier wave. There are many types of signal modulation, and there are many types of demodulators. The signal output from a demodulator may represent sound, images or binary data. Wikipedia →
