Which of the following is an appropriate receive filter to select in order to minimize noise and interference for SSB reception?

For Single Sideband (SSB) reception, the goal is to effectively isolate the desired signal from noise and interference while avoiding distortion of the audio. A filter designed to minimize noise and interference is most effective when it closely matches the bandwidth of the signal being received.

In SSB communication, audio frequencies are typically in the range of 300 to 3000 Hz. A filter with a bandwidth of 2400 Hz is capable of passing the necessary audio frequencies for SSB reception while still excluding much of the unwanted noise and interference.

A narrower filter, such as 500 Hz or 1000 Hz, could potentially limit the audio fidelity of the signal, leading to difficulties in understanding the transmitted message. Conversely, a wider filter, like 5000 Hz, would allow too much surrounding noise and interference into the reception, defeating the purpose of filtering.

Thus, a 2400 Hz filter provides a good balance by allowing adequate bandwidth for the SSB signal, while also filtering out much of the extraneous noise, making it the most appropriate choice for effective SSB reception.
