this looks like a question given to you in a test or something but anyway type fdatool into the command window in matlab, choose the fir, bandpass configuration chosse different windows, look at the magnitude and phase response, the idea is to get a low order filder with the desired transition width. if you are completely new to filter desin you might wanna read through this first: **broken link removed**
