Research on the Function and Application of Some Classical Combinational Logic Products

Abstract

Digital signals are discrete and discontinuous signals both in time and quantity. The circuits used for digital signal processing are digital circuits. Digital electronics came into being. It is a fully developed technology, through the construction and use of specific digital circuits to achieve the logical operation of digital quantities and required logical functions. Therefore, the basic characteristic of digital circuit system is logical operation and logical processing function. The main applications of digital electronic technology are combinational logic circuit, sequential logic circuit, pulse waveform generation and shaping, digital and analog conversion circuit, etc. Here only describes the practical application products of combinatorial logic circuit and sequential logic circuit, namely decoder and counter.
