A Polyphase Transfer Function Design Based on Frequency Transformation from Prototype LPF
Cosy Muto · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2008
In this paper, a frequency transformation for designing polyphase transfer functions is proposed. A modification to the bilinear LP-LP transformation, which assigns both stopband edges on negative frequency range whereas passband edges are on positive one, results polyphase transfer functions. Design examples show validity of the proposed method.
