The Design of Signal Generator based on Virtual Instrument

摘要

The paper design a Virtual Signal Generator based on Virtual Instrument, which can produce continuous adjustable amplitude and frequency signal. It's contains of the most basic three waveform: sine wave, pulse wave and triangle wave. We design the signal generator by LabVIEW. Data acquisition is NIUSB-6009. By the measurement we can seen from function to output signal parameters of the virtual signal generator are similar as the results of actual measurement.
