Doubt in Matlab bandpass filtering

[badash_123]

Hi

I have a waveform and I need to filter it using a band pass filter to allow frequencies 30 to 70 Mhz. How do I make matlab accept my waveform as its input when doing filtering? I can calculate the co efficients by giving my specifications and I do not know how to give my waveform as an argument. Can somebody help me with the exact function that does this ? Thanks

are you using a specific ready filter in matlab or are you writing the code for it by yourself?

Thanks for the reply. I am using a ready filter using fdesign.bandpass function.

Will filter(b,1,waveform) work if b is the co efficients found using fdatool and waveform is my input waveform ?Please reply. Thanks
