| Abstract: | The signal sender based on single-chip microcomputer is good at data deposit, DDS-chip control, LCD switch and extent transfer of digital potential unit. The sinusoidal wave and the square wave caused by DDS-chip enhance the speed and liability of the system. Any wave type with loading capacity can be got from CPLD by data transition, model conversion and current recuition. |
