Switched-capacitor filter

A switched-capacitor filter is like a special kind of tool that can change how something sounds. It has these special things called capacitors that can hold energy and let it go at different times.

Think of it like a toy bucket with holes in it. You fill the bucket with water and then cover up the holes with your hand. When you take your hand away, some of the water comes out and it goes into another bucket. This is kind of like how a switched-capacitor filter works. It moves energy from one place to another by using those special capacitors.

When we use a switched-capacitor filter to change how something sounds, we have to tell it what to do. It's like asking a friend to give you a different toy to play with. We set up the filter to do what we want by using something called a clock. This clock helps control when the energy goes through the filter and when it comes out.

Overall, a switched-capacitor filter helps us change how things sound by using special capacitors and a clock to move energy from one place to another.
