Analysis Of The Influence Of Emi On Digital Signal In Cable Bundle

In recent years,with the rapid development of science and technology,lots of electronic products are widely used in daily production and life.There is a very important problem that the electromagnetic interference in electronic equipment or electrical systems.Almost every electronic device produces electromagnetic interference signals of varying degrees,which are harmful electromagnetic signals.Such signals can be emitted in the form of electromagnetic radiation or transmitted through current-carrying conductors,such as power lines,cables,etc.And almost all electronic devices are sensitive to interference from other electronic devices.Because electromagnetic interference signals have a great influence on low-voltage electronic circuits.For digital circuits,it can easily lead to changes in signal levels,which will affect the accuracy of data link transmission.In order to ensure the normal operation of electrical or electronic systems,electromagnetic interference is a problem that cannot be ignored.Therefore,this paper studies the digital signal in the cable bundle,and simulates the degree of interference that the digital signal may suffer by constructing a simulation circuit model about the cable bundle.Further analysis will lead to the influencing factors of digital signal distortion,and solve some of the interference problems.This paper mainly studies and analyses the influence of EMI on digital signals in the cable bundle.The main tasks are as follows: First,conduct in-depth investigations of EMI at home and abroad,expounding relevant theoretical knowledge and the current research status of the influence and suppression of EMI on digital signal.Second,through software such as SACAMOS,LTspice,Rstudio and MATLAB carry out circuit simulation simulation.Third,carry out a large number of simulation simulations to obtain data,and conduct comparative analysis to explore the influence of EMI on digital signals.Fourth,design an LMS-based adaptive filter based on the influence of EMI,and build a filter simulation circuit model.Fifth,summarize all the results of this paper and the deficiencies in the experiment and the goals that need improvement.
