DSBSC (Double Sideband Suppressed Carrier) modulation

Double Sideband Suppressed Carrier (DSB-SC) modulation is a broadcasting method where a message signal (like voice or data) is combined with a high-frequency carrier wave. Unlike traditional AM, the carrier is suppressed, meaning only the two sidebands containing the actual information are transmitted. This makes the transmission more efficient because less power is wasted on the carrier. On the receiving end, the original message can be recovered by reintroducing the carrier signal. DSB-SC is widely used for efficient communication systems, such as in radio and telecommunications.
