CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis
classes.engineering.wustl.eduThe plot of sinusoidal voltage versus time is shown in Figure 3.1 below. Our first observation is that a sinusoidal function is periodic. A periodic function is defined such that y (t) = y (t + T) where T is called the period of the function and is the length of time it takes the sinusoidal function to pass through all of its possible values.
