Efficient computation of universal weights for maximally flat (atπ /2) linear -phase integrators of various degrees
In a host of signal processing situations, the desired (ideal) frequency response of the filter is a rational function H(omega) =1/(jomega) (a digital integrator). In such cases, IIR filters can be exploited but at the sacrifice of linearity of phase response. However, FIR structures are preferred to the IIR ones due to wellknown advantages of the former. We may also essentially require the FIR filter with its magnitude response having maximal flatness at omega=pi/2.
