ABSTRACT

A new active low pass filter comprising of two general purpose operational amplifiers (OAs), four resistors and one capacitor is presented. The analytical expressions are obtained and the performance of the proposed circuit is examined in relation to the conventional circuit. Simulation and experimental results are presented which establish the superiority of the proposed low pass filter on the conventional circuit.
