The degree to which the design technique produces acceptable

The degree to which the design technique produces acceptable filter designs depends in part on the number of filter coefficients selected.

A. True

B. False

This question was posed to me during a job interview.

This intriguing question originated from Pade Approximation Method topic in portion Digital Filters Design of Digital Signal Processing

Right choice is A. True

The explanation is: The degree to which the design technique produces acceptable filter designs depends in part on the number of filter coefficients selected. Since the design method matches hd(n) only up to the number of filter parameters, the more complex the filter, the better the approximation to hd(n).
