Document Summary
Let"s examine the response of the circuit shown on figure 1. The form of the source voltage vs is shown on figure 2. The general response is given by: vc t tp. Figure 2. t as a function of the p and vp . vc t. 0 t tp (1. 1) the capacitor voltage at t tp= is equal to vp . Therefore for times t tp> the vc t tp t. A general plot of the response is shown on figure 3 for. If the pulse becomes narrower, the value of vc will not reach the maximum value. By expanding the exponential in equation (1. 1) we obtain, 1 the higher order terms may be neglected resulting in. At the end of the pulse (at vc t (cid:17) Rc e (1. 6) is the area of the pulse and thus the response is proportional to that tp . Impulse response of rc circuit t tp> the response becomes.
