Could you please solve this question in MATLAB

FIR Filter Design Use the sinc equation in Matlab to design: ith a cut-off frequency 0.2T 2 A high pass filter with a cut-off frequency -0.7T.

Solution

Matlab code:

%for 0.2pi

fi = fdesign.isinclp(\'N,Fp,Fst\',50,0.1,.2);
lp = design(d,\'SincFrequencyFactor\',0.25,\'SincPower\',16);
fvtool(lp, \'MagnitudeDisplay\', \'Magnitude\');
%for 0.7pi
fi2 = fdesign.isinclp(\'N,Fp,Fst\',50,0.1,.7);
lp2 = design(d,\'SincFrequencyFactor\',0.25,\'SincPower\',16);
fvtool(lp2, \'MagnitudeDisplay\', \'Magnitude\');
