Demodulation – Definition and Pronunciation
What is Demodulation?
Demodulation is the process of retrieving information impressed upon a carrier wave during the process of modulation. Demodulation along with Forward Error Correction (FEC) aims at recovery of the original signal or data being transmitted with a high level of fidelity (extremely low Bit Error Rate).
Examples of Demodulation
However, frequency – modulated transmissions provide better quality reception because the demodulation process can reject weak interfering transmissions as well as substantial amounts of amplitude – varying interference (e. g., from electrical storms, electrical machinery and spark ignition systems).
From “Basic transmitters and receivers in shipping”.
Demodulation is the recovery, from a modulated carrier, of a signal having the same characteristics as the original modulating signal. The underlying analog carrier is superimposed with a digital signal, typically using 4-, or 8-point Phase Shift Keying (PSK) techniques, or 16-point Quadrature Amplitude Modulation (QAM).
