Which of the following receiver filter bandwidths provides the best signal-to-noise ratio for SSB reception?
Pick an answer to check it.
Answer: C. 2400 Hz
An SSB voice signal is about 2.4 to 3 kHz wide. A 2400 Hz filter passes the voice while blocking extra noise, giving the best signal-to-noise ratio. 500 Hz and 1000 Hz are too narrow for voice (they suit CW), and 5000 Hz lets in more noise.
Tip: SSB = 2400 Hz, CW = 500 Hz.
