Analog all-pass filter having a T-element

摘要

An analog all-pass filter in the form of a T-element having a coil with a tap in the longitudinal branch and having a first capacitor (C1) in the transverse branch, the coil being bridged by a second capacitor (C2). In order to level the attenuation response at high frequencies, the coil parts on both sides of the tap are each supplemented by a third (C3) and fourth (C4) capacitor respectively to form rejection circuits, and the first capacitor (C1) is bridged inductively (L2). <IMAGE>
