Abstract: This system take FPGA as a core, profile generator, frequency meter and digital voltmeter organic synthesis in together. FPGA has the rich resources, the easy to operate is nimble, and easy to carry on the function to expand, definitely may satisfy the design the request. The main module has the profile to produce the module, the frequency establishment module, the digital-analog conversion module, the display module and the filter network. And FPGA uses for to realize the wave form production and the frequency control; The sine wave digital-analog conversion realizes by DAC8032; The reshaping uses triode S9018 to realize; And enhances the output wave shape through the low pass filter the quality. This design uses double DA to control the profile the scope, has realized the scope continuously adjustable. key word: FPGA Double D/A amplitude modulation Digital-analog conversion 目 录
