· What is Electromagnetic Interference? Electromagnetic interference (or EMI) is a disruption that affects an electrical circuit because of either electromagnetic induction or externally emitted electromagnetic radiation. EMI is the interference from one electrical or electronic system to another caused by the electromagnetic fields generated by its operation.

Noise occurring in bursts at a rate of 120 bursts per second, and the resulting characteristic raspy buzz or frying sound, is often the first and most obvious clue of power-line interference. It is typically a broad banded type of noise starting at the low end of the radio spectrum. Power-line noise is usually stronger on lower frequencies.
· How to get rid of hum and eliminate other noises from your audio and video systems Don't let buzz, hum, or hiss ruin your AV experience. We'll show you how to
· Selecting capacitors with lower ESR and ESL will lower noise, but be careful, some power-supply circuits use the ESR to provide the error signal for feedback. If you reduce it radically, say, by
RF/coaxial connectors, such as SMA, are often found on test fixtures or on prototype board designs. Attaching a TDP7700 series probe to these on-board connectors is easy with the SMA adapter. The P77C292MM adapter allows you to connect to 2.92 mm, 3.5 mm or SMA connectors with full bandwidth and low noise.

· For a low-resistance multi- layered screen, this screening factor can be 35 dB or 3000 times. Twisting of the signal wires provides a slight improvement in the induced noise voltage by ensuring that C1 and C2 are closer together in value thus ensuring that any noise voltages induced in the signal wires tend to cancel one another out.

· Electrostatic noise is one, which is transmitted through various capacitances present in the system such as between wires within a cable, between power and signal cables, between wires to ground or between two windings of a transformer. These capacitances present low-impedance paths when noise voltages of high frequency are present.
· In the US, 4.4 million metric tons of e-waste were recycled in US formal electronic recycling (e-recycling) facilities in 2011 , which constitute only 25% of all e-waste generated (U.S. EPA, 2011). Part of the world's e-waste is recycled in informal e-waste sites in developing countries, such as Agbogbloshie in Ghana ( Kyere et al., 2016 ).
