Electronics systems face threats from numerous sources. A system that is required to operate for a long period of time must be designed competently and well protected from these menaces. The nuisance signals come from a variety of sources such as ESD (Electrostatic Discharge), EFT (Electrical Fast Transient), Lightening, or the power source itself. The mitigation strategy to protect the system must consider all these threats and design the system in such a way that can withstand and safeguard against any and all possible threats.
