Signal transition graphs
Okay kiddo, do you know what a signal is? It's like a message that gets sent from one place to another. Like when you call your friend on the phone, your voice is a signal that goes through the phone wires to your friend's phone.
Now, let's say we want to show how a signal changes over time. That's where a signal transition graph comes in. It's like a map of how the signal changes.
Think of it like a game where you have to follow a path. Each circle on the graph is a stopping point on that path. At each circle, the signal might stay the same (we call that a stable state) or it might change in some way.
The lines between the circles show how the signal can move from one state to another. Sometimes there are arrows on the lines to show which way the signal can move.
For example, let's say we're talking about a traffic light. The signal is either red or green, right? So we could draw a signal transition graph with two circles: one for "red" and one for "green". There'd be a line with an arrow pointing from "red" to "green" to show that the signal can change from red to green. And there'd be another line with an arrow pointing from "green" to "red" to show that the signal can change back again. That's a simple signal transition graph!
Does that make sense, kiddo?
