本章将涉及比较深层的 MATLAB 内容：脚本；函数（一般函数、内联函数、子函数、 私用函数、方法函数）；程序调试和剖析；数据结构（类、对象）；重载和继承；面向对象 编程。本章配备了许多精心设计的算例。这些算例是完整的，可直接演练的。读者通过这些 算例，将真切感受到抽象概念的内涵、各指令间的协调，将从感知上领悟到面向对象编程的 优越和至关要领。(MATLAB )

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four D flip flops. Draw a state transition diagram, a state table and a schematic for your circuit. Design an alternate implementation using just three flip flops and draw a state transition diagram, state table and a schematic for your circuit. If your designs are extended to implement an n bit twisted ring counter, how many flip flops are required using each of the two approaches. In what situations would you prefer the first method? In what situations would you prefer the second?
