Abstract

This paper presents a new class of variable multi-output passive digital filters. By changing the values of the filter coefficients, the characteristics of the frequency responses of these passive digital filters can be varied. These variable multi-output passive digital filters include first-order and second-order lowpass and highpass digital filters, and second-order bandpass and bandstop digital filters. 2D and 3D variable multi-output passive digital filters can be obtained by appropriate combinations of 1D digital filters. Simulation results are given to illustrate their frequency response variability.
