Abstract

A new type of second-order digital parametric equalizer is proposed whose frequency response matches closely that of its analog counterpart throughout the Nyquist interval and does not suffer from the prewarping effect of the bilinear transformation near the Nyquist frequency. Closed-form design equations and direct-form and lattice realizations are derived.
