4.1 Introduction

Electromagnetic interference (EMI) is an upshot of terrific escalation of electronics and telecommunication in the modern society. All electronic devices emanate magnetic and electrical energy, and this energy unintentionally integrates with another device and generates electromagnetic interference. The EMI among electronic appliances ...
