Fig. U.b.1: The AD2 has only 5-volt-max waveform generators. To drive 3 LEDs in series with two load resistors, closer to 8-V is required. Hence, the circuit below uses an op-amp voltage amplifier (which will be build in Lab 4), with a 10 X gain to drive the rectifier circuit. The power supply consists of two 12-V household AC/DC adapters.


Fig. U.b.2: Example how to connect AD2 cable to a breadboard.


The rectifier circuit is modified to add a large 470 uF capacitor.
