This simplified … WebSo to get the phase response, we find the z-transform, replace z with e j ω and solve for the angle. Consider then the z-transform for a simple symmetric odd length (Type 1) FIR Filter with coefficients as: [ c 1, c 2, c 3, c 2, c 1] The z-transform would be: H ( z) = c 1 + c 2 z − 1 + c 3 z − 2 + c 2 z − 3 + c 1 z − 4.
WebFIR filters are usually designed to be linear-phase, although they don't have to be. Like we discussed earlier, a FIR filter is linear-phase if ... the filter coefficients are symmetric or anti-symmetric. So for an N-th order filter, the number of multiplications can be reduced from N to N/2 for N even and to (N+1)/2 for N odd.
