The article explains the use of a standard microcontroller with a small memory in lieu of a direct-digital-synthesis (DDS) device for generating signals for audio and low-frequency circuit systems. The microcontroller should be programmed as a DDS to drive an audio digital-to-analog converter (DAC). Figures are used to illustrate the microcontroller, the integrators that produce an analog feedback loop like the typical resonators and the sine wave curve produced by the software.
