Convolution Integral: How a Graphical Type of Solution Can Help Minimize Misconceptions

A physical system, Low Pass Filter (LPF) RC Circuit, which serves as an impulse response and a square wave input signal are utilized to derive the continuous time convolution (convolution integrals). How set up limits of integration correctly how excitation source convolves with explained using graphical type solution. This in turn, help minimize students’ misconceptions about integral. Further, effect varying circuit elements on shape output plot is presented allowing students see connection between integral system. PSpice simulation experiment results incorporated compared those analytical solution associated
