CHEBYSHEV FILTER DOENS'T WORK WHEN I TRY BANDPASS

[fenny]

I want to try bandpass filtering, so I chnaged the input paremeters of Chebyshev filter accoridng to help.
I set high-cut-off frequency to be 1500Hz, and set low-cut-off frequency to be 0 Hz. SAmpling rate is 10000 Hz.
I selected filter type to be"band pass", after I run the program, no data came out from the filter. I don't know why?

I have not tried it but I suspect that your input parameter Low-Cutoff Frequency = 0 may be the problem. This would imply a low pass filter, not a bandpass. Try it with a frequency of 500 Hz and see if it works.
