Question
How does a speech processor affect a single sideband phone signal?
Answer Options
- A) It increases peak power
- B) It increases average power
- C) It reduces harmonic distortion
- D) It reduces intermodulation distortion
Correct Answer: B
Explanation
The primary goal of a speech processor is to improve the efficiency of Single Sideband (SSB) communication by utilizing the transmitter’s capacity more fully. Human speech is very ‘peaky,’ and without processing, the transmitter spends most of its time operating at low power.
By compressing the dynamic range of the voice, the processor allows the operator to increase the overall signal level, resulting in an increase in average power output. This higher average power is what improves the signal-to-noise ratio and makes the signal more readable at the distant station.
