ECE 225 ELECTRONIC CIRCUITS LABORATORY EXPERIMENT #2 1. Construct the bandpass filter shown in Fig.(1) using op amp 741. (a) What is the value of Q and the center frequency 0 f , which are defined by the following equation: V o / V s (j ϖ ) = A o / [1 + j Q ( ϖ / ϖ 0 - ϖ 0 / ϖ ) ] (b) Check the response using an oscilloscope. (c) What is the maximum input voltage to avoid clipping. 2. Construct the 4 th order Butterworth filter of Fig. (2) using op amp 741. (R=10 K)

(c) Check the filter response and determine the slope of the response above 10 kHz. 3. Prelab (a) Assuming it is an ideal op amp, derive ( ) s V j V for Fig. (1). (b) Use SPICE to generate Bode magnitude and phase plots for the circuits in Fig. (1) and Fig. (2)....
