Digital all-pass networks
Sanjit K. Mitra,K. Hirano +1 more
TL;DR: In this paper, a systematic method is outlined to realize an m th-order all-pass digital transfer function using only m multipliers as a cascade of first-order and/or second-order sections.
Journal ArticleDOI
Design of digital notch filters
TL;DR: It is shown that a second-order digital notch filter is uniquely characterized by two distinct parameters, the notch frequency and the 3-dB rejection bandwidth, as a result, such a filter can be realized using only two multipliers.

TL;DR: In this paper, the authors developed a design technique for approximating nonseparable frequency characteristics by sums and products of separable transfer functions, called the piecewise separable decomposition of the characteristic.
