Design and implementation of the virtual oscilloscope

LI Zong-lian

Abstract

In this paper the authors build a virtual oscilloscope on PC by the virtual instrument software LabVIEW for signal analysing,processing,testing,etc.The data acquisition card is used to get circuit signals and data are read into the computer,therefore the functions of this virtual dual-trace oscilloscope such as the mV meter,Frequency meter are realized.
