What is Electromagnetic filters?
An electromagnetic filter is an electrical circuit designed to prevent electromagnetic waves from damaging a device or system. These waves can be high-frequency electrical and magnetic fields that disrupt or degrade the performance of the device. Electromagnetic filters reduce the effect of electromagnetic waves on the device by being placed at the input and output of the device, helping the device to function properly.

How to read it? On the left: noisy input, center: Filter, right: clean output. Increase the noise, then adjust cutoff — watch how high-frequency components are suppressed and the output becomes smoother.
Types of Electromagnetic Filters
Electromagnetic filters are used in electronic devices, computers, automatic control systems, and other electrical devices. These filters improve the performance of the device and regulate its operation by reducing the effect of electromagnetic waves on the device. Electromagnetic filters are placed at the input and output of the device to reduce the effect of electromagnetic waves on the device and help the device to function properly.
Types of electromagnetic filters can vary based on the design of the filter. For example, electromagnetic filters can be:
+ Limiting filters: These filters limit high-frequency electrical noise and regulate the operation of the device.
+ Power supply filters: These filters reduce electromagnetic waves from the power supply and regulate the operation of the device.
+ Magnetic filters: These filters reduce magnetic fields and regulate the operation of the device.
+ Bandpass filters: These filters filter out specific frequency ranges and regulate the operation of the device.
+ Combination filters: These filters combine multiple filter designs and regulate the operation of the device.
