hi

i have the following code:

filter = fdesign.bandpass(.4,.48,.52,.60,80,1,80);
BandPassFilt = design(filter, 'equiripple');
C=filter(BandPassFilt,smps);

but i get error:
??? Error using ==> subsindex
Function 'subsindex' is not defined for values of class
'dfilt.dffir'.


what's the problem?

Hi Michael,
Do not assign your filter design output to a variable called 'filter'
because that creates a conflict with the filter function.

This works fine:

>> f = fdesign.bandpass(.4,.48,.52,.60,80,1,80);
>> BandPassFilt = design(f, 'equiripple');
>> C = filter(BandPassFilt,randn(10,1))
