Explanation:
Detailed explanation-1: -Demodulation is the obtained of baseband data from the transition band signal. In other words, on the receiving side, the information signal is obtained again from high-frequency carrier signals. The demodulation of the signal with a stable and simple receiver structure improves communication performance.
Detailed explanation-2: -Demodulation is defined as extracting the original information-carrying signal from a modulated carrier wave. A demodulator is an electronic circuit mainly used to recover the information content from the modulated carrier wave.
