In this paper describers a new and interesting notch distributed RC networks configuration that realizes an all-pass network function is proposed. The circuit is presented with which an all-pass transfer function of arbitrary order, having simple negative real poles, has been realized by combining the output of notch distributed RC networks with a portion of its input in a differential amplifier. The experimental results for such an all-pass function is also indicated. This network circuit has the advantage that the gain constant of all-pass function may be varied by varying the gain of differential amplifier.
