When you come to class, bring a calculator and some paper. We will start by doing some exercises where you will compute equivalent resistances. We will then talk about how to use resistors to condition signals form sensors.
In the lab wednesday and thursday, you will plug together some resistor networks, measure the resulting resistances with a multimeter, put input signals to the networks with a signal generator and look at the various signals with an oscilloscope. The lab will introduce you to using a multimeter, a signal generator, and an oscilloscope. Optionally, you may solder together a resistor network and get some experience with a soldering iron.
