Unformatted text preview: bandwidth as well as maximum attenuation. Calculate Q from the bandwidth. Compare these frequency characteristics with those expected? + V out V in _ Op amp C R C R R 1 R 2 + _ Op amp C R C R R 3 R 4 1 _ LF 356 V out V in R 1 C + C R 2 R 3 The report should contain: A) The two frequency plots (done using MATLAB) and: All frequency plots should be in dB versus log f . The frequency plots for the 4 th order Butterworth and Resonant bandpass filter should also show a plot of the ‘theoretical’ frequency plot obtained in MATLAB using the transfer function. (Substitute jω for s in the transfer function, transcribe into MATLAB code, and evaluate for values of ω over a least 3 orders of magnitude.) B) A Table showing calculated and measured values of the gain, the maximum slopes, and BW for circuits 1 and 2 and the Q for circuit 2. 2...
