%% Information on a Lowpass FIR Filter
% Design a lowpass FIR filter with normalized passband frequency 0.4\pi rad/sample and normalized stopband frequency 0.45\pi rad/sample. Obtain information about the filter just designed.

d = designfilt('lowpassfir','PassbandFrequency',0.4,'StopbandFrequency',0.45);
s = info(d)
