Analog signal processing

Analog signal processing is when you take an electrical signal that is shaped like waves and manipulate it. Think of a wave like a wiggly line. With analog signal processing, we can take the wave and adjust it in different ways. We can make it louder, stretch it, and make it smaller. We use it in things like radios, televisions, and phones to make them work properly. It's a way of taking the signals that machines send from one another and changing them so that they make sense.
