Question

What is the reason for the need of high speed DSP?

(a) Less power consumption at higher speeds

(b) Better processing capabilities

(c) High sampling frequency

(d) Easily programmable

This question was addressed to me in a national level competition.

This interesting question is from Digital Signal Processing in portion Digital Communication Techniques of Avionics

Answer 1

The correct answer is (c) High sampling frequency

The best I can explain: The time taken for input/output and the processing time together must be smaller than the sampling period to ensure the continuous flow of data. Since high sampling frequencies are needed for accurately converting the analog signal to digital, high speed DSP is a must.
