d = fdesign.lowpass('Fp,Fst,Ap,Ast',1,3,0.5,40,60);
  1. 1 is the passband frequency
  2. 3 is the stopband frequency so the region between 1 and 3 Hz is a transition region
  3. 0.5 is the passband ripple in dB
  4. 40 is the amount of stopband attentuation you want in dB
  5. 60 is the sampling frequency

Hello,
how can you apply a cut off frequency with this command?
d = fdesign.lowpass('Fp,Fst,Ap,Ast',1,3,0.5,40,60);
