Abstract:

The traditional teaching of Digit Electronic Technology usually limits students' understanding  of concepts and theories to the static state circuit so that they can not construct a concrete and direct viewing learning mode.This paper introduces a circuit analysis and simulation software Multisim into teaching.It designs and analyzes the priority encoder 74LS148 simulation circuit by the Multisim software.By Multisim,the structure,analysis,coding principle,and dynamic running of the simulation circuit as well as the analysis of the result are shown,which can help students further understand abstract concepts and theories and improves the teaching effect.

Key words: Multisim;digit electronic technology;circuit simulation
