Quel principe n'est pas associé au traitement des signaux analogiques?
- ALa compression
- BLa limitation de la largeur de bande
- CL'écrêtage
- DLa division de fréquence
Correct answer: D — La division de fréquence. Question tirée de la banque officielle d'ISDE.
Why
Frequency division is not a core principle of analog signal processing because it describes a method of sharing a communication channel by assigning different frequency slots to separate signals, which is a multiplexing technique rather than a way to shape or alter a single analog waveform itself. The full explanation — and one for every question — is in Pro.
