Noise on commercial power lines could enter the equipment and disturb the proper function.
Noise generated by the equipment for example from switch mode power supplies need to be filtered and the spread of such generated noise need to be suppressed.
Common-mode suppression chokes together with line bypass capacitors building an AC EMI suppression filter device.
