| Abstract: | In order to overcome that the present medical electronic instrument cannot produce and measure physiological signal simultaneously, a muhifimctien produce and measurement instrument for physiological signal was put forward. STM32F207VG is used as the core, while the program was written by the C language, and compiled by the Keil C. It could not only output high precision phase and controllable common signal sine wave, square wave and triangle wave, and measure up to eight channel physiological signal, but also produce the conventional physiological signals, for example cardiogram, heart sounds, pulse wave. And the common clinical abnormal physiological signals also can be produced by it. In addition, the instrument had a high drive ability of interface, which could be directly driven headphones etc.h can be widely used in scientific research, teaching, testing and instrument maintenance and so on. |
