What is the reason for using a properly adjusted speech processor with a single-sideband voice transmitter?
- A It reduces average transmitter power requirements
- B It reduces unwanted noise pickup from the microphone
- C It improves voice frequency fidelity
- D It improves the intelligibility of your signal
Correct answer: D — It improves the intelligibility of your signal. From the official ISED question bank, verified word for word.
Why
A properly adjusted speech processor boosts the quieter parts of your voice while limiting the loudest peaks, which raises the average volume of your transmission without overloading the transmitter. The full explanation — and one for every question — is in Pro.
