Title: Solving a RLC Circuit using Convolution with DERIVE for Windows Michel Beaudin Abstract: It is quite easy with a Computer Algebra System to use a "Dsolve" command in order to find, for example, the capacitor voltage in a RLC circuit: we only have to solve the corresponding differential equation. We will present a method using convolution: this is important because understanding convolution of signals is a difficult concept for students. We will consider an RLC circuit with zero initial conditions and with variable electromotive force (emf): this is a good example of a linear, time-invariant (LTI) system. And, if the input emf is periodic, the steady-state output is also periodic: this could be used to introduce Fourier series!
