In this article, a model of the diode ring modulator is developed, which is based on a model from the literature, but modified to suit musical applications. After a brief introduction to analog ring modulation, a substitute circuit for the diode ring modulator is presented and analyzed, leading to a system of ordinary differential equations (ODEs) of first order. The equations are solved by using Euler’s method. The model is compared with a real ring modulator using the same input waveforms, showing a good match between the simulation and the real device.
