What is frequency sampling method in FIR?
The frequency sampling method allows us to design recursive and nonrecursive FIR filters for both standard frequency selective and filters with arbitrary frequency response.What is the advantages of frequency sampling technique in FIR filter design?
Merits of frequency sampling technique
(i) Unlike the window method, this technique can be used for any given magnitude response. (ii) This method is useful for the design of non-prototype filters where the desired magnitude response can take any irregular shape.How to design a 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).- The frequency sampling method can be used to design a filter with an arbitrary frequency response such as H(?) . To have simpler mathematical expressions, we can approximate H(?) using the red curve in the following figure.29 sept. 2017
