How does a speech processor affect a single sideband phone signal?
- A.It increases peak power
- B.It increases average power (correct answer)
- C.It reduces harmonic distortion
- D.It reduces intermodulation distortion
WhyA speech processor increases a single sideband phone signal's average power. By compressing an SSB voice signal's peaks, a speech processor lets the average power the transmitter puts out increase, even though the signal's peak envelope power stays essentially capped by the amplifier's rating, answer B. It doesn't raise peak power (that's set by the amplifier), and it isn't a distortion-reduction tool, if anything, overdone processing can add harmonic and intermodulation distortion rather than reduce it.
