Which of the following functions is not included in a typical digital signal processor?
- A Analog to digital converter
- B Digital to analog converter
- C Mathematical transform
- D Aliasing amplifier
Correct answer: D — Aliasing amplifier. From the official ISED question bank, verified word for word.
Why
An "Aliasing amplifier" does not exist because aliasing is an unwanted error that happens when sampling is too slow, not a function any device performs. The full explanation — and one for every question — is in Pro.
