| Abstract: | Virtual Instrument technology as the core, combined with the aid of computer sound cards and other hardware resources, using LabVlEW software development platform designed a dual-channel sound card based Signal Generator. Dual-channel signal generator through the sound card D / A channel output waveform signal, you can produce sine, square, triangle,sawtooth wave and arbitrary waveform. With parameter settings, feature selection, signal output time-domain waveform monitoring and other functions. The signal generator has a powerful, user-friendly, more convenient to use, etc.Virtual signal generator and the improved greatly save funds research, has a good application prospect. |
