Which two components are involved in the signal processing of a single sideband receiver?

The correct choice highlights two essential components in the signal processing of a single sideband receiver: the audio frequency amplifier and the product detector.

In a single sideband (SSB) receiver, the product detector plays a crucial role by mixing the incoming SSB signal with a local oscillator signal. This process helps to recover the original audio frequencies from the modulated RF signal. By demodulating the signal, the product detector separates the voice or data information contained in the sideband signal from the carrier frequency, allowing it to be amplified for listening or further processing.

Following the demodulation process, the audio frequency amplifier is responsible for increasing the strength of the audio signal, making it audible through speakers or more manageable for digital processing. Without these two components, effective signal processing in SSB communication would not be possible, as they work together to ensure that the transmitted audio is successfully decoded and enhanced for the operator to understand.

In contrast, while the other components listed might play important roles in a broader receiver context, they do not directly contribute to the specific signal processing required for single sideband communication. For example, an RF amplifier and filter are typically involved in the initial stages of signal reception, and power supply and output stages relate to the overall operation
