Abstract

In this paper, we developed a signal generation method which can be used in the interferential current electrical stimulating device. A low-cost, 8-bit microcontroller and a very compact algorithm were adopted here to generate the sine wave. Using the method, we can easily modify the frequency and phase difference between two channels with high resolution. The preliminary experiment shows that this method can reduce the circuit complexity and improve the signal stability
