What are the design methods for FIR filter?
Constrained Least SquaresMinimize squared integral error over entire frequency range subject to maximum error constraintsArbitrary ResponseArbitrary responses, including nonlinear phase and complex filtersRaised CosineLowpass response with smooth, sinusoidal transition
How to design an FIR filter using frequency sampling method?
Procedure for Type-1 Design:
1 Choose the desired frequency response Hd(?)2 Sample Hd(?) at N -points by taking ?=?k=2?kN where k=0,1,2,3,…( 3 The N-point inverse DFT of the sequence H(k) gives the impulse response of the filter h( n).
