What is DSB-SC demodulation?

DSB-SC (Double Sideband Suppressed Carrier) demodulation is a process used to retrieve the original message signal from a modulated carrier wave that has been transmitted without its carrier component. The demodulation typically involves multiplying the received DSB-SC signal by a locally generated carrier wave at the same frequency and phase as the original carrier. This multiplication process results in the recovery of the message signal, which can then be filtered to remove unwanted frequencies. DSB-SC demodulation is efficient and widely used in communication systems due to its bandwidth efficiency and reduced power requirements.
