| Abstract: | On the basis of the principle of DDS, the system hardware of achieving the arbitrary waveform generator （AWG） is de- signed by taking Cyclone II series chip EP2CSQ208C as the platform. Combining with the characteristics of DDS＇s output signals, the two kinds of low pass filter are designed to implement the filter processing for output signals and the application program for the user is developed on LabWindows/CVI platform as well. The AWG is able to generate sine wave, square wave, triangle wave and sawtooth wave as user＇s demands. |
