If you remove both low and high frequencies, you're left with nothing at all!

If you have R2018a, use the bandpass (link) function to design a bandpass filter for your signal. Choose the frequencies you wan to retain as the limits of the filter passband. There are also other methods of designing filters in MATLAB.
