Circuit arrangement for simulating a resistive elementary two port device for use in a wave digital filter

摘要

A wave two port circuit arrangement for simulating a resistive elementary port two device for use in a wave digital filter. First and second ports are each arranged for receiving input and output signals. A summing device is connected to the first and second ports and produces a sum signal which represents the sum of the input signals present at the first and second ports. A multiplier is connected to the summing device and to one of the first and second ports for producing a negatively scaled sum signal and feeding it to the one port as part of the output signal present at that port.
