The experience students obtained from
the mechanical systems in the previous four labs can be applied to study
electrical systems. Systems with masses, springs and dampers have their
electrical equivalents with respectively inductors, capacitors and resistors.
A major difference between electrical and mechanical systems is that with
electrical systems you can achieve nearly ideal behavior far more easily.
In this lab, the transfer functions of a few first-order electrical systems,
shown in figure 1, are measured. The students measure the circuit step
response and frequency response functions.

The hardware we need for this lab consists of a signal generator, an
oscilloscope and a breadboard to easily put together the electrical components
as shown in figure 2.
