A general FIR filter does not have a linear phase response but Specification necessary for Window Design Method Response must not enter shaded regions
Design of FIR Filters
(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 (iv) A method or algorithm is selected to find the best filter transfer function
