**10.1 ***Introduction*

Consider the experiment illustrated in Figure 10.1-1. Here, a function generator provides the input to a linear circuit and the oscilloscope displays the output, or response, of the linear circuit. The linear circuit itself consists of resistors, capacitors, inductors, and perhaps dependent sources and/or op amps. The function generator allows us to choose from several types of input function. These input functions are called waveforms or waves. A typical function generator will provide square waves, pulse waves, triangular waves, and sinusoidal waves.

The output of the circuit will consist of two parts: a transient part that dies out as time increases and a steady-state part that persists. Typically, the transient part dies out quickly, perhaps in a couple of milliseconds. We expect that the oscilloscope in Figure ...
