Summary :

Generalized expressions for variable transfer functions (VIFs) , v(f,x) , for approximating real transmission chracteristic y₀(f)^u are investigated, which results in several new VTFs that provide error reductions and/or realizations superior to conventional ones. Error reduction is attained through zero forcing (ZF) of errors in terms of u and/or x parameters (ZF- U, ZF-X). It is shown that error reduction for first order VTFs (Linear and bilinear VTFs) depends only on ZF-U. On the other hand, second order VTFs (quadratic and biquadratic VTFs) utilize both ZF-U and ZF-X to attain drastic error reductions. The concept of x range modification is also introduced to contribute design flexibility.
