PURPOSE:To increase the transmission speed of a signal by amplitude shift modulation by providing a sequential correlation arithmetic means so as to realize demodulation with no distortion and fast leading, converting a demodulated waveform and decoding the waveform into a mark space information code ...
The demodulation process depends on the type of modulation employed. For DSB-AM and SSB-AM, the demodulation method is coherent demodulation, which requires the existence of a signal with the same frequency and phase of the carrier at the receiver. For conventional AM, envelope detectors are use...

They suggest that the sensory system operates through a vibratory amplitude modulation/demodulation scheme. Fine textural properties are encoded in the time-varying envelope of the whisker-resonant vibrations. This quantity is then recovered by neural demodulation, as it effectively drives the spiking-...

Modulation is the process of varying a carrier signal to transmit information. Demodulation is the reverse process, extracting the original information from the modulated signal.
