What is Hamming window FIR filter?

The reduction and filtering of the input components of an original signal in one or more frequency bands using a finite impulse response, better known as FIR, is designed using a function of the Hamming window.

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.

How to create a Hamming window in Matlab?

w = hamming( L ) returns an L -point symmetric Hamming window. w = hamming( L , sflag ) returns a Hamming window using the window sampling specified by sflag .

What does Hamming do in Matlab?

hamming( Length ) returns a symmetric Hamming window object with length Length . Length must be a positive integer. Entering a positive noninteger value for Length rounds the length to the nearest integer.
