几个练习使用Labview编程的产物，主要包括：1.正弦扫频信号发生器，可选择频率变化规律（不变、线性、指数变化）以及幅度变化规律（不变、线性、指数变化），还可以通过MathScript节点自定义频率、幅度变化规律； 2.声卡数据采集及频谱分析；3.会说话的小圆点；4.十六进制数布尔数组显示；5.在字符串中显示多种字体；6.钢琴键盘模拟(Several products by practicing Labview programming, including: 1 Sine sweep signal generator, selectable frequency variation (constant, linear, exponential change) and amplitude variation (constant, linear, exponential changes), you can also customize the frequency and amplitude variation through MathScript Node 2 sound card data acquisition and spectrum analysis 3 talking dots 4 hexadecimal to boolean array display 5 display a variety of fonts in the string 6. Piano keyboard simulation )

此例子主要讲述图像在labview下的模式匹配及图像分割！(This example focuses on image matching and image split mode under labview!)

初步使用，与获取信号，需要自己组装各子VI实现所需功能(Initial use, with the acquisition of signals, requires the assembly of each of its sub VI to achieve the desired function)
