Abstract :
A new single amplifier (infinite gain) symmetrical notch network is described where the pole positions are defined by the transmission zeroes of an RC parallel-T circuit. It is shown that the structure described has an independently adjustable notch depth and is relatively insensitive to amplifier gain variations.
