What is the purpose of a speech processor in a transceiver?
- A.Increase the apparent loudness of transmitted voice signals (correct answer)
- B.Increase transmitter bass response for more natural-sounding SSB signals
- C.Prevent distortion of voice signals
- D.Decrease high-frequency voice output to prevent out-of-band operation
WhyA speech processor in a transceiver increases the apparent loudness of transmitted voice signals. A speech processor compresses the dynamic range of a voice signal, raising the average level of quieter passages closer to the peaks, which makes the transmitted voice sound louder and punch through noise better, answer A. It doesn't specifically boost bass response, it doesn't prevent distortion (used too aggressively it can cause it), and it isn't there to trim high frequencies for band-edge compliance.
