A generalisation scheme of the active RC allpass networks with one differential input operational amplifier and three RC 2-ports is presented. The 2-ports are unbalanced, but not earthed, and only the voltage transfer functions of these networks are used in this generalisation, thus making the analysis of the circuit and the circuit transfer functions considerably easier.

Inspec keywords: linear network analysis; transfer functions; active filters
