Document Summary
Time dependent sources: in general the sources connected to a circuit can be time varying. A commonly used time dependent source is a sinusoidal source such as tv. Some definitions associated with the signal shown in figure 1 include: Amplitude: the amplitude of the sinusoidal function shown in figure 1 is va. The peak-to-peak amplitude of the function is 2va. Cycle: a cycle is the smallest repeated pattern that can be used to regenerate the entire waveform. Beginning at any specific point on the waveform, that has a certain amplitude and slope, one cycle is completed after the shortest amount of time needed to return to that same amplitude and slope on the waveform. Period: the period, t, as shown in figure 1 is the length of time required for one complete cycle. Frequency: this is given in cycles per second or hertz (hz), such that the frequency is one over the period, or.
