Lab B5

Two options for Lab B5:

1. Analog filter design: Design a three-channel audio spectrum analyzer, with fourth-order band-pass filters and corners at 20 Hz, 200 Hz, 2 kHz, and 20 kHz (at least three channels and at least fourth order; more would be better).
2. Analog computer design: Read Section 12.3 in Roberge's Operational Amplifiers. Simulate and build the scaled analog computer for Van der Pol's Equation in Figure 12.16. Then, simulate and build an analog computer for Duffing's Equation (or some other interesting differential equation in consultation with the staff).
