可调方波发生器，可以控制方波的幅值，频率，占空比。,Adjustable square wave generator, square wave to control the amplitude, frequency, duty cycle.

矩形波发生器:输出频率范围为10HZ-1KHZ,输出电压为5V,且占空比10％-90％可调,输出频率也可调节-Rectangular-wave generator: output frequency range of 10HZ-1KHZ, output voltage of 5V, and 10-90 duty cycle adjustable output frequency is also adjustable

实现正弦波、三角波、方波的选择，且可以中途刷新；波形的相关参数如幅度、初始相位、频率可调。每周期波形所取的点数由 用户确定。 -Achieve sinusoidal, triangle wave, square wave of selection, and can be set half-way waveform parameters such as amplitude, initial phase, frequency adjustable. Waveform per cycle c
