Question

In general, an FIR system is described by the difference equation y(n)=\(\sum_{k=0}^{M-1}b_k x(n-k)\).

(a) True

(b) False

This question was addressed to me in an interview for internship.

The query is from Structures for FIR Systems in chapter Discrete Time Systems Implementation of Digital Signal Processing

Answer 1

Right answer is (a) True

For explanation: The difference equation y(n)=\(\sum_{k=0}^{M-1}b_k x(n-k)\) describes the FIR system.
