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Mathscr ipt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 Mathscr ipt 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.
