Advanced Qualification · A-005 Transmitters, modulation and processing · A-005-007-008
Laquelle des méthodes suivantes n'est pas utilisée pour limiter les crêtes dans le traitement des signaux?
- AL'écrêtage d'un signal audio
- BL'écrêtage spectral
- CL'écrêtage d'un signal RF
- DLa compression
Correct answer: B — L'écrêtage spectral. Question tirée de la banque officielle d'ISDE.
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.
