Abstract

This paper presents a new electronically tunable standard notch, low pass notch and high pass notch filters. All the filters can be obtained from the same topology by adjusting a grounded resistance. The electronic tuning of the notch frequency, the zero frequency and the pole frequency can be achieved by adjusting the gain of a voltage-amplifier connected in the feedback path of the proposed topology without disturbing the constituents of the filter itself; that is a shadow filter Experimental results obtained using the AD844 current-feedback operational amplifier are included.
