Question

Determine the filter coefficients h(n) for frequency response of the filter (10) using frequency sampling method (1s1=7)

Answer 1

Explanation:

This article will review the basics of the frequency sampling method for designing Finite Impulse Response (FIR) filters.

FIR filters have two main advantages over Infinite Impulse Response (IIR) filters:

An FIR filter has no feedback loop and is inherently stable. (We always need to check the stability of an IIR filter.)

An FIR filter can easily provide a linear-phase response, which is crucial in phase-sensitive applications such as data communications, seismology, etc.

This article will teach you how to design an FIR filter using the frequency sampling method.
