Π-cascade crossfunction digital filter with arbitraryzeros
Abdesselam Klouche-Djedid · Electronics Letters · 1996
Gray–Markel digital filters for lossless realisations and the lossless bounded real (LBR) structures have transmission zeros constrained to 0, infmity or the unit circle. This results in cross-transfer function synthesis with low stopband sensitivity. In the Letter, a cross-function synthesis with arbitrary zeros is proposed. A design example is provided.
