Description: design LP,HP,B S digital Butterworth and Chebyshev
filter. All array has been specified internally,so user only need to
input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify
the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,...,
ksection and the freq.-design LP, HP, B S digital Butterworth and Chebyshev filter. A 'll array has been specified internally. so user only need to input f1, f2, f3, f4, fs (in hz). alpha1. alpha2 (in db) and iband (to specify the type of t o design). This program output hk (z) = bk (z)/ak (z), k = 1,2 ,..., ksection and the freq. Platform: |
