Abstract
The invention relates to an arbitrary waveform generation method of an electric acupuncture apparatus, and belongs to the technical field of electronic medical equipment. A master controller of the electric acupuncture apparatus can obtain waveform envelope data and pulse type parameters through a touch screen and a keyboard, the data is stored into a memory, then the data is sequentially read out from the memory, processed and then conveyed into a digital-analog converter, the digital-analog converter is used for transforming digital waveform quantity to analog voltage quantity, high-frequency noise is removed through a low-pass filter, and then the analog voltage quantity enters an analog amplifying circuit for achieving the required amplitude. The controller can send out the data in a circulating manner, and the required circulating waveform can be produced.
