Question

Explain EMI control techniques.

Answer 1

Electromagnetic interference (EMI) is increasing as a result of higher clock speeds in today's PCs and workstations. ...

One powerful method to reduce EMI is the spread spectrum technique which modulates the signal and spreads the energy over a wider frequency range. ...

The modulation method is a very simple concept.

Answer 2

Answer:

$\huge\bold\green{ANSWER:-}$

EMI suppression involves grounding, shielding, and filtering. 1. Grounding. An ideal ground plane is a zero-potential, zero impedance body that can be used as a reference for all signals in associated circuitry, and to which any undesired current can be transferred for the elimination of its effects.
