Design of FIR Hilbert transformers and differentiators by eigenfilter
Soo-Chang Pei, Jong-Jy Shyu · IEEE Transactions on Circuits and Systems · 1988
The design of Hilbert transformers and differentiators by eigenfilters is presented. The filter coefficients are computed from an eigenvector of an appropriate real, symmetric, and positive-definite matrix. The method is simple, and the performance is better than that of McClellan-Parks algorithm. The design time is fast and comparable for filter length less than one hundred.>
