Optimal Modelling of (1 + <i>α</i>) Order Butterworth Filter under the CFE Framework
This paper presents the optimal rational approximation of (1+<i>α</i>) order Butterworth filter, where α ∊ (0,1) under the continued fraction expansion framework, by employing a new cost function. Two simple techniques based on the constrained optimization and the optimal pole-zero place...
