How do you design a FIR filter with windows?
To design an FIR filter by windowing, you first decide on an ideal frequency response and calculate the impulse response of the ideal frequency response. You then truncate the impulse response to produce a finite number of coefficients.Which window is best for FIR filter design?
It is concluded that Black man window is the best window, because its side lobe is the better than another window. Key words—FIR filter, hamming window, Kaiser window, Gaussian window, and window.What is the design method of FIR filter?
They are as follows: (i) A desired or ideal response is chosen, usually in the frequency domain. (ii) An allowed class of filters is chosen (e.g. the length N for a FIR filters). (iii) A measure of the quality of approximation is chosen.- Windows are sometimes used in the design of digital filters, in particular to convert an "ideal" impulse response of infinite duration, such as a sinc function, to a finite impulse response (FIR) filter design. That is called the window method.
