Which of the following is not a method used for peak limiting, in a signal processor?
- A Frequency clipping
- B RF clipping
- C Compression
- D AF clipping
Correct answer: A — Frequency clipping. From the official ISED question bank, verified word for word.
Why
Frequency clipping is not a real method for peak limiting because clipping means cutting off the top of a signal wave, which happens with voltage or amplitude, not with the frequency itself. The full explanation — and one for every question — is in Pro.
