The transfer function of a 2nd order active LPF is generally written as equation (1). In (1), o, is the cut-off frequency, A, is the pass-band gain and a is the damping coefficient. Assuming A, is 20DB and o, is 1KHZ. Plot the frequency response of the filter for different damping coefficients (0.5, 0.766, 0.866, 1.06, 1.42, 1.73). Please note that the damping coefficient could be changed by changing A0 (discussed in the class). 2 Aowe s+ dwcS twe HCS) : (1) 2
