| Abstract: | An arbitrary waveform generator(AWG)which is designed by MCU and CPLD has been studied and developed. The paper also introduces two methods based on MATLAB for waveform data acquisition in detail.Experiment proved that the sys- tem can generate various standard function waveforms and arbitrary waveform signals whose frequency and amplitude can be adjust- ed.The signal obtained by this means proved to be having high frequency resolution and accuracy with the meet of bandwidth. |
