What is AC noise filter?

First it stops noise from entering and disrupting the operation of your electrical equipment. Secondly, it stops your electrical equipment from putting EMI/RFI noise onto the power lines. The first is to protect your equipment from malfunction or failure. The second is to protect other electrical equipment.

How does an electric noise filter work?

Different EMI line filters suppress specific frequencies of noise while allowing others to flow unimpeded. After the filtering process, electromagnetic noise gets diverted away from the device and to the ground. Some EMI filters may also route unwanted currents back to the noise source or absorb them.

How do I stop my AC line from making noise?

You can use a filter to remove noise from a power supply just like you use filters to remove noise from a signal. Indeed, you can consider the output capacitors part of a filter that reacts against the output impedance of the power-supply circuit. Increasing the value of the output capacitance will reduce noise.

What is an AC line interference filter?

A line filter is the kind of electronic filter that is placed between electronic equipment and a line external to it, to attenuate conducted radio frequencies -- RFI, also known as electromagnetic interference (EMI) -- between the line and the equipment.
