Acquisition of FDM Signal by Using Sound Card Based on LabVIEW

Abstract:

Taking the computer sound card instead of current acquisition card as hardware and Labview as software development platform, a kind of sound card data acquisition system with higher sampling precision, middling sampling frequency and better flexibility is designed, it is given an example of six-path analog input multiplexing．It has realized data acquisition of multi-path FDM(frequence division multiplexing) signal. The system has many advantages, for example, high cost performance, strong commonality, and good expansibility．It takes on wider foreground in the fields of engineering measure and laboratory application．
