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

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);
