Multiplier-free IIR Filter Realizations with Periodically Time-Varying Coefficients
Tantaratana, Sawasd 대한전자공학회 1996 APCCAS:Asia Pacific Conference on Circuits And Sys Vol.1 No.1
In this paper, we extend the periodically time-varying (PTV) filter realization, which was proposed for FIR filter, to be used for IIR filters. The realization consists of ternary ({0,±1}) or quinary ({0,±1,±2}) PTV coefficients with simple input and output units. The coefficients as well as the input and output units require no hardware multiplier. This simplifies the layout for VLSI implementation and increases the processing speed.
