2. Electromagnetic Interference (EMI)
• Electromagnetic interference (EMI) refers to the disturbance or
noise that can affect the performance of electronic devices and
systems when they are exposed to electromagnetic fields.
• EMI can disrupt the normal functioning of electronic equipment by
inducing unwanted electrical currents or voltages.
• It can occur through various means, such as electromagnetic
radiation from nearby devices, power surges, or electromagnetic
waves from sources like radio transmitters

4. Conducted And Radiated Noise
• Conducted noise, also known as conducted interference or
conducted EMI (Electromagnetic Interference), refers to unwanted
electrical disturbances or noise that travels through physical
conductors like wires, cables, or traces on a printed circuit board
(PCB).
• Radiated noise, also referred to as radiated interference or
radiated electromagnetic interference (EMI), is unwanted
electromagnetic radiation that propagates through the air as
electromagnetic waves.

5. Electromagnetic And Electrostatic
• Electromagnetic fields can be defined as the combination of
electric and magnetic field.
• Electrostatics can be referred to as a branch of physics that
studies current free charge distribution.

6. Common Impedance Coupling
Common impedance coupling, also known as common
impedance coupling (CIC), is a type of electromagnetic
interference (EMI) or noise coupling mechanism in
electronic systems. It occurs when multiple circuits or
components within a system share a common impedance,
such as a common ground or power supply line.
