%% Generate FIR Filter with Direct Form I Transposed Structure
% Design a 30th-order FIR filter using the window method. Specify a cutoff
% frequency of _&pi;_/4 rad/sample. Create a Simulink(R) block with a
% direct form I transposed structure.

b = fir1(30,0.25);
filt2block(b,'FilterStructure','directFormTransposed')
