用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

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 的。您仅仅需要学会如何使用一个单一的函数集就可以在多种编程环境中对大部分NI 数据硬件进行编 程。 (Since the release of NI-DAQmx, NI data acquisition (DAQ) users take full advantage of its many features, these characteristics are developed in order to save Time and designed to improve the performance of data acquisition applications. A large part of the development time-saving features a NI-DAQmx application programming interface (API), which function in a variety of equipment And equipment series are the same. This means that all the functions of a multifunction device by the same set of functions programming (analog input Into, analog output, digital I/O and counter). Moreover, a digital I/O device, and an analog output device can use the same letter Number set programming to get. LabVIEW, polymorphism, and thus can achieve. A polymorphic VI to accept a variety of data classes Type for one or more input and/or output terminals. NI-DAQmx API it supports all programming environment is consistent s. You just need to learn how to use a single set of functions can)
