UNDERSTANDING as the DSB-SC signal’s suppressed carrier.

UNDERSTANDING DSB-SC DEMODULATION THROUGH SIMULINK   ? THEORY :   The incoming DSB-SC signal is multiplied by a pure sine wave that must be the same frequency as the DSB-SC signal’s suppressed carrier. This sine wave is generated by the receiver and is known as the local carrier.   To see why this process recovers the message, let’s describe product detection :                DSB-SC demodulator’s output = the DSB-SC signal X the local carrier.         ?
