Question

The major advantage of designing linear phase FIR filter using frequency sampling method lies in the efficient frequency sampling structure.

(a) True

(b) False

I had been asked this question at a job interview.

My question comes from Design of Linear Phase FIR Filters by Frequency Sampling Method topic in portion Digital Filters Design of Digital Signal Processing

Answer 1

Right answer is (a) True

Easy explanation: Although the frequency sampling method provides us with another means for designing linear phase FIR filters, its major advantage lies in the efficient frequency sampling structure, which is obtained when most of the frequency samples are zero.
