Realization of first-order two-dimensional all-pass digital filters

Supplementary First-Order All-Pass Filters with Two Grounded Passive Elements Using FDCCII

In this study, two novel first-order all-pass filters are proposed using only one grounded resistor and one grounded capacitor along with a fully differential current conveyor (FDCCII). There is no element-matching restriction. The presented all-pass filter circuits can be made electronically tunable due to the electronic resistors. Furthermore, the presented circuits enjoy high-input impedance...

A note on "Realization of first-order two-dimensional all-pass digital filters"

The compromise for achieving this efficiency is the dependency of the programs length on the length of the transform, i.e., for longer transforms longer programs are generated. But the complexity order of the program length is N loglog N, and the proportionality constant is small, resulting in the program lengths shown in Table IV. These results are of real practical significance and can be imm...

Single DV-DXCCII Based Voltage Controlled First Order All-pass Filter with Inverting and Non-inverting responses

In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...
