%% Highpass Filter Transfer Function % Design a 6th-order highpass FIR filter with a passband frequency of 75 % kHz and a passband ripple of 0.2 dB. Specify a sample rate of 200 kHz. % Compute the coefficients of the equivalent transfer function. %% hpFilt = designfilt('highpassiir','FilterOrder',6, ... 'PassbandFrequency',75e3,'PassbandRipple',0.2, ... 'SampleRate',200e3); [b,a] = tf(hpFilt)
