ABSTRACT:
An active filter which utilizes a single operational amplifier in conjunction with a plurality of resistance-capacitance (R-C) elements, to simulate either an inductance-capacitance (L-C) or a resistance-frequency dependent negative impedance (R-D) network, in which only one impedance constraint must be met in order to realize the network.
