simple counters Counting is a fundamental function of digital circuits. A digital counter consists of a collection of flip-flops that change states (set or reset) in a prescribed sequence

FLIP-FLOPS Add the certain combinational logic circuit to the input of the original flip- flop New

第一章数字电路基础 1.1数字电路的基本概念 一、数字信号的特点 数字信号在时间上和数值上均是离散的。 数字信号在电路中常表现为突变的电压或电流
