Which principle is not associated with analog signal processing?
- A Clipping
- B Frequency division
- C Compression
- D Bandwidth limiting
Correct answer: B — Frequency division. From the official ISED question bank, verified word for word.
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.
