Description: This VI tells you the time delay between two analog input signal. For example, if you have two microphone with three meter space between them, and you make a clap, then the VI calculate the time delay with crosscorrelation and with maximum value serching. From the time delay it calculate the distance difference between the two microphone and the soundsource. Platform: |

Description: 自从NI-DAQmx 发布以来，NI 数据采集(DAQ)用户就充分利用了它的许多特性，这些特性是为节省开发
时间和提高数据采集应用程序的性能而设计的。
一个能节省相当大一部分开发时间的特性是NI-DAQmx 应用程序编程接口（API），它在各种设备功能
和设备系列中都是相同的。这就意味着一个多功能设备的所有功能可由同样的函数集编程得到（模拟输
入、模拟输出、数字I/O 和计数器）。而且，一个数字I/O 设备和一个模拟输出设备都可使用相同的函
数集编程得到。在LabVIEW 中，由于多态机制，因而这是可以实现的。一个多态的VI 接受各种数据类
型以用于一个或多个输入和/或输出终端。NI-DAQmx API 在它所支持的所有编程环境中也是保持一致

Description: The trend of miniaturization in electronics has led to greater heat densities within computer chips, demanding high performance heat sinks at smaller and smaller scales.
The equation used within VI program is used to calculate the resistance of the thermistor with respect to the excitation voltage and the temperature excitation can be used.
We will read an output voltage on labview, of the temperature detected by the LM35, by using a serial input, and analog output by the DAQ (motor).
