Abstract :
A new complex-pole allpass network is described which is based on the minimum-transmission properties of an RC parallel-T network. The proposed structure is compared with the canonic Deliyannis arrangement, and analytical and experimental evidence is presented which indicates an improved sensitivity to finite-amplifier-gain effects.
