Abstract—This paper deisgns a new kind of electrical appartus which developed by programmable logic devices FPGA and produce 2Hz ,100Hz sine and rectangular wave signals based on the direct digital frequency synthesis principle.By testing,the frequency of output signal is precise,the output waveforms are stable.Because of using FPGA,the Peripheral equipments are fewer,with design flexible,field programmable,easy debugged and small volume.
Keywords—A Electric apparatus; DDS; FPGA
