How to design linear phase FIR filter?

The most straightforward approach to the linear phase FIR filter design is the frequency sampling method. After a design is completed, the amplitude response A (co) is specified at N typically equidistant points or frequency samples.

How to design FIR filter using window in matlab?

b = fir1(___, window ) designs the filter using the vector specified in window and any of the arguments from previous syntaxes. b = fir1(___, scaleopt ) additionally specifies whether or not the magnitude response of the filter is normalized. Note: Use fir2 for windowed filters with arbitrary frequency response.
