    1.采用Labview设计一虚拟函数信号发生器, 通过数据采集卡输出波形信号,调节信号的相关参数,可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口; ⑵ 数据采集卡输出多种信号,至少完成三种波形:正弦波、三角波、方波(可调占空比)的输出,同时前面板上显示各输出波形; ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比(0~100 )等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

    虚拟仪器的网络控制 1)、设计一个程序控制8个外设小灯的点亮方式,要求两种方式A:每个小灯间隔时间T,依次亮,时间T可调,并循环。B:先1.3.5.7.9亮隔时间T,2.4.6.8.10亮,并循环,T可调。 2)、要求主面板与硬件的8个小灯同步。 3)、通过网络在另一台计算机上控制此程序的运行(利用LabVIEW的DateSocket技术)((Network control of virtual instruments 1), design a program to control eight peripheral lights lit the way, the requirements in two ways A: each light interval T, followed by bright, time T adjustable, and circulation. B: first 1.3.5.7.9 bright every time T, 2.4.6.8.10 light, and circulating T-adjustable. 2), requires eight small lights of the main panel and hardware synchronization. 3), through the network control of this program running on another computer (using the LabVIEW DateSocket technology)))
