以LABVIEW可视化图形编程开发环境为平台，使用声卡和数据采集卡测量和显示在1MIN和0.5MIN内的脉搏数。-LABVIEW graphical programming with visual development environment for the platform, use the sound card and data acquisition measurement and display in 1MIN and 0.5MIN the pulse number.

In this paper we present the implementation of a digital lock-in amplifier (LIA) completely based on Labview with a general-purpose data acquisition board (or a high quality sound card) and a high-gain low-noise amplifier
