Question

The foregoing approach for determining the poles and zeros of H(z) is sometimes called Prony’s method.

(a) True

(b) False

I have been asked this question by my college director while I was bunking the class.

The above asked question is from Least Squares Design Methods topic in chapter Digital Filters Design of Digital Signal Processing

Answer 1

The correct option is (a) True

Easy explanation: We find the coefficients {bk} by pade approximation and find the coefficients {ak} by least squares method. Thus the foregoing approach for determining the poles and zeros of H(z) is sometimes called as Prony’s method.
