[Design and simulation of interference current therapeutic instruments based on FPGA].
This paper applies the DDFS theory, uses the method based on the Look-Up-Table, and designs an interference current therapeutic instrument with the automatic frequency scanning module and DDFS module to generate two different interference currents. The design of every module and the whole system are simulated by quartus II, the result shows that the design principle is correct and feasible, and worthy of applications.
