Design Of The Multifunctional Electrotherapeutical Instrument Based On FPGA

In allusion to the defect of the electrotherapeutical instrument in market, such as single function, output of fixed frequency, the multifunctional electrotherapeutical instrument is designed. The field programmable gate array (FPGA) is used as the critical device, it implements to out and control the electrotherapeutical frequency, the output activates the body of people to cure.The content of this paper include: (1) It devides the electrotherapeutical frequency into three frequency segment, and introduces the treatment effect of each frequency segment. ( 2 ) It overviews the EDA technology and the characteristics of FPGA device. ( 3 ) It describes the design method of the whole system implementing to out and control in detail, it contains the design of hardware circuit and software; Because the output of fixed frequency activates the body of people, and the body creat adaptability, the output frequency is random frequency, this output effectively avoids to adopt the body to the signal, can acquire the better purpose. (4 ) In order to...
