What is the purpose of a speech processor in a transceiver?

  1. Increase the apparent loudness of transmitted voice signalsՃիշտ պատասխան
  2. Increase transmitter bass response for more natural-sounding SSB signals
  3. Prevent distortion of voice signals
  4. Decrease high-frequency voice output to prevent out-of-band operation

Բացատրություն

A speech processor compresses or clips the dynamic range of the audio so that the average level sits much closer to the peak level. Since peak envelope power stays at the same limit, more average power is transmitted and the signal sounds louder at the receiving end.
