- 实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出.-Achieve the four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency and amplitude controlled output.
quadrature
- The output from incremental optical encoders and from many other types of measurement devices is known as a “quadrature” signal. A quadrature signal consists of two square waves 90° out of phase. The input channel on our encoder interface board count

- 今天的微控制器速度已经可以通过软件轻而易举地实现这一切。而且更妙的是电压表和电流表成了免 费的副产品。微控制器的控制环无论如何都必须知道电压和电流值。你刚好也要显示它。我们要从微控制 器得到的是：一个在所有时间都用来测量电压和电流的A/D 转换器；一个根据命令为功率三极管提供基准 电压的D/A 转换器。问题是那个D/A 转换器的速度要非常快。如果在输出端检测到了短路，那么我们必 须立即减小三极管B 极上的电压，否则这个三极管就会损坏。“快速”意味着要达到毫秒级，如同运算放 大
