Abstract :
Sound card is a multi-channel digital and analog signal conversion system each other. It can replace data acquisition card in some virtual instruments. A virtual oscilloscope and function waveform generator have been designed to use lab VIEW and sound card. The oscilloscope can accurately display the external signals acquisitioned by sound card. The function waveform generator can produce sine waveform, square waveform, triangle waveform, saw tooth waveform, Gaussian white noise waveform, tones and sine waveform and formula waveform. The amplitude of these signals are within 1V and the frequency of these signals are within the scope of 20Hz to 20kHz. It proves virtual instrument based on sound card that can be applied to data acquisition and control applications.
