So it has a complex dynamical behavior and is widely used in all kinds of circuit, for example the pulse digital circuit and analog circuit. Due to the different of circuit’s form and signal source and the parameter of the capacitance or resistance make up the various application forms of the RC circuit. This paper analyzes the Integral circuit and differential circuit, filter circuit, coupling circuit and RC phase-shift circuit and pulse pressure circuit’s principle and way of working . And we can find that because the change of the relationship between the capacitance and resistance’s output or input relationship and dealing with the waveform, Its volt-ampere characteristics will be different. RC circuit mainly as a kind of signal transmission circuit, It can achieve filtering, phase shift, coupling, and other functions in different situations. And it will realize the waveform’s production and conversion, etc when the step voltage working. And this paper will proceed comparison of theory in time domain and frequency domain, finding out the differences and relations, establish a unified understanding.
