To produce a single-sideband suppressed carrier transmission, it is necessary to ____ the carrier and to ____ the unwanted sideband.

In single-sideband suppressed carrier (SSBSC) transmission, the goal is to enhance efficiency and reduce bandwidth by minimizing unnecessary components of the signal. This process involves two key actions: canceling the carrier and filtering out the unwanted sideband.

Canceling the carrier means that the power of the carrier wave—typically a strong component of amplitude modulation—is eliminated. This reduction is crucial because in traditional amplitude modulation (AM), the carrier carries no intelligence and consumes power, which is not needed in SSB transmission.

Filtering the unwanted sideband is the next vital step. In SSB transmission, only one sideband (either upper or lower) carries the necessary information, while the other sideband is redundant and can be discarded. By effectively filtering out the unwanted sideband, the transmission can use bandwidth more efficiently and ensure that only the relevant information is transmitted.

These processes together allow SSB transmissions to be more efficient compared to traditional AM, making them ideal for situations such as amateur radio and various forms of communication where bandwidth and power efficiency are crucial.
