Mm'-type filter

Okay, so imagine you are trying to drink some juice from a cup, but there are some yucky bits in it that you don't want to drink. You might use a strainer or a filter to get rid of those yucky bits and only drink the clean juice. A mm'-type filter works kind of like that, but instead of getting rid of yucky bits in juice, it gets rid of signals that you don't want in your electronics.

When you have electronics like a radio or a phone, they might pick up signals from other things around them like a microwave or a Wi-Fi router. These signals can be really annoying because they might make your electronics not work as well or even make weird noises. So, using a mm'-type filter can help you get rid of those unwanted signals.

The mm'-type filter is like a really fancy strainer that uses tiny wires and circuits to get rid of only the signals you don't want. It's kind of like having a bunch of tiny strainers all working together to filter out the yucky bits. That way, you can get a better signal for your electronics and enjoy them without all the unwanted interference.
