Speech compression associated with SSB transmission implies:
- Afull amplification of high level signals reducing or eliminating signals amplification of low level
- Ba lower signal-to-noise ratio
- Ccircuit level instability
- Dfull amplification of low level signals reducing or eliminating amplification high level signals
Correct answer: D — full amplification of low level signals reducing or eliminating amplification high level signals. From the official ISED question bank, verified word for word.
Why
Speech compression works by boosting quiet parts of your voice so they travel farther, while keeping loud parts from getting too strong and causing distortion. The full explanation — and one for every question — is in Pro.
