Oscilloscope

基于labview的FIR数字滤波器课程设计文档，附vi程序(FIR digital filter based on LabVIEW curriculum design document, attached to the VI program)

编写软件为labview2011，功能为读取txt文件中的值，并绘制电平图，设置了双游标，可以自动准确计算出两游标X轴时间差值。txt的内容为上升沿或下降沿的时间信息，首位0代表下降沿，1代表上升沿。后面位的值乘16代表沿的绝对时间(program software is the labview2011, functions is to read txt file values​ ​ , and draw level diagram, set up a dual cursors, you can automatically and accurately calculate the time difference between the two cursors X axis. txt contents of rising or falling time information, the first 0 represents falling, a representative of the rising edge. Followed by 16-bit value represents absolute time along)

自功率谱是分析非平稳信号频谱的重要手段。对于非平稳信号来说，利用自功率谱分析能够更容易找到信号中能量聚集区域，对信号中的频率分布有更好的了解。本文件中将其制作成独立子VI方便程序直接调用。(Self power spectrum is an important method to analyze the spectrum of non-stationary signals. For non-stationary signals, it is easier to find the energy accumulation region in the signal by using self power spectrum analysis, and better understand the frequency distribution in the signal. This document will be made into an independent sub VI convenience program to call directly.)

说明：  Labview程序，方便大家学习交流，关于labview的程序，都是整理好的 ，仅供参考。(LabVIEW program, convenient for everyone to learn and exchange, about the LabVIEW program, are sorted out, for reference only.)

LabVIEW脉搏波采集程序，可以控制采集的开始和停止(Pulse acquisition of LabVIEW)

读取keithley数据的labview程序(Read keithley data labview program)

labview使用xy绘图控件时对于有的需求要对图像做归一化处理(LabVIEW with XY drawing to achieve normalization)

使用labview实现中断访问串口，使用消息队列方式传递数据。(Use labview realize interrupt visit, use the message queue serial port style to deliver data. )

说明：  labview读取 cad dxf文档,包括圆直线线段等等(read CAD dxf include circle line)

该vi主要是一台简单的单通道数字示波器，实现数据采集、波形显示、信号处理、波形存储等(The main vi is a simple single-channel digital oscilloscope, data acquisition, waveform display, signal processing, waveform storage, etc.)
