Alright class, settle down, let’s take a look, At this word ‘signal,’ and what it really took! The dictionary gives us a helpful clue, “A sequence of states, for me and you!” Let's break it down with a little rhyme, To make this concept truly sublime. Think of a radio, clear and bright, Sending out waves throughout the night. That voice you hear, a message sent, Is a signal – carefully meant! It’s made of changes, on and off it goes, A coded pattern that everyone knows. “Encoded message” is key to see, Information packed for you and me. And "communication channel" - think of the way, The signal travels, day by day! (Like through wires or air, hey!) So a signal isn’t just one single sound, But a series of changes all around. It's how we send data, quick and neat, A structured pattern, bittersweet! Does that make sense? Any questions you see? Let’s discuss this ‘signal’ carefully!

Alright class, settle down now, let’s take a look! That dictionary definition – quite precise and neat – really breaks down what “signals” truly meet. Let's unpack it together, nice and slow, so the meaning starts to brightly glow. “A sequence of states…” Think of it like a code, you see? A pattern built for you and me! Like Morse Code dots and dashes, a rhythmic beat, Each one tells a story, bittersweet. “…representing an encoded message…” Now this is key, my friends! It’s not just random, it has intent. Think of a secret code, cleverly penned, A hidden meaning, carefully sent. “…in a communication channel.” This means it travels far and wide, you know? Through wires or waves, wherever they flow, Carrying information, to and fro! So, essentially, a signal is a way to talk, Using patterns that are clear as the chalk. It's how we send our thoughts, both big and small, Responding to messages, answering the call! Do you have any questions about this concept? Don’t be shy, let your curiosity fly!
