Abstract
Electromagnetic Interference (EMI) is a significantchallenge that affects signal integrity in modern highspeed and mixed-signal electronic circuits. This project presents a comparative analysis of EMI radiation between single-ended and differential-endedtransmission methods. The circuits were designed and simulated using Proteus software, where both singleended and differential-ended configurations were implemented to observe the oscilloscope readings. The waveform-based EMI and EMC characteristics were further analysed using LT-spice, where the signal generation and field variations were studied to understand radiated emission behaviour. The results clearly show that differential-ended signalling offers superior noise immunity and lower electromagnetic emission levels compared to single-ended transmission.This is primarily due to the balanced current flow that causes mutual field cancellation. The study highlights that adopting differential pair design and proper PCB layout practices are crucial for minimizing EMI inembedded and communication systems.
