1.	Given the following circuit, find the maximum gain.(a) 1+R2/R1(b) –R3/R2(c) 1+R3/R2(d) 1+ R1.R3/2I got this question in exam.The doubt is from Frequency Filters topic in division Op-amps and its Applications of Analog Circuits
Answer» Right CHOICE is (c) 1+R3/R2 The explanation is: The above CIRCUIT is a LOW pass filter of the non-inverting type, where the input is at the non-inverting END. The GAIN is A = 1+R3/R2 / 1+jωR1C1 Thus maximum gain is A = 1+R3/R2.
