ELECTROMAGNETIC INTERFERENCE PHILOSOPHY

All form of electronic equipment particularly radio frequency communication equipment suffer from electrical and magnetic inference. To electronic system such signal constitute of serious form of pollution the effect of some part of the radiofrequency (RF) spectrum which is a natural. Ineffective management of the spectrum results in electromagnetic interference (EMI) in which either telecommunication systems are susceptible to service disruption from other services, or they causes and sources of EMI as well as its disruptive effects on system such as Global positioning systems, aircraft and medical devices. Various means of mitigating the effects of EMI or protecting equipment against EMI. THE wide use of electronic circuits, for communication computation and automation, makes necessary for divers circuit to operate in close proximity to each other.
