Useful Simple Equivalents of Uniformly Distributed R-C (URC)
Umesh Kumar · 1981
Simple single 7r and T section equivalents ofURC notch filters are presented which have been developed using the technique postulated in a previous paper. The models are deemed to be of considerable use in practical design and analysis owing to their much improved simplicity. Frequency selective characteristics can be obtained by the notch configuration without the use of a conventional inductor whose fabrication in semiconductor integrated circuit form poses considerable difficulty. The null characteristic is usually obtained by placing a resistor in series with the capacitive terminal of the RC structure, as proposed originally by Kaufman. 2 Two-port modelling of notch
