Part III Figure 2a shows a circuit for a full adder, which has the inputs a, b, and ci, and produces the outputs s and co. Parts b and c of the figure show a circuit symbol and truth table for the full adder, which produces the two-bit binary sum cos = a + b + ci. Figure 2d shows how four instances of this full adder entity can be used to design a circuit that adds two four-bit numbers. This type of circuit is usually called a ripple-carry adder, because of the way that the carry signals are passed from one full adder to the next. Write VHDL code that implements this circuit, as described below. 2

脉宽调制 （PWM） 或脉冲宽度调制 (PDM) 是一种调制技术， 确认的脉冲宽度正式的脉冲持续时间，基于调制器信号信息。 尽管这种调制技术可以用来编码信息的传输，它的主要用途 是允许控制的电气设备，尤其是供电的对惯性载荷，如 电动机。 各种通信处理器的重要元素是脉冲宽度调制器 (PWM)。还 此 PWM 是不同功率控制单位。此元素可以作为 PWM 或计时器工作。它具有 16 位 主要的计时器，它可以叉骨界面时钟，是免费提供总线接口之间进行选择
