Signal analysis is like trying to understand what someone is saying when they speak in a different language or accent.
Just like how you would try to break down the different sounds and syllables in their speech, signal analysis tries to break down the different components of a signal (sound, light, or any type of data).
This helps you understand more about the signal, such as its frequency (how many times it repeats in a certain amount of time), amplitude (how high or low the signal is), and other characteristics that can tell you more about what the signal is and what it represents.
By analyzing these different components, you can better understand signals in your environment, such as music, speech or even data transmitted over the internet, and use that information to make decisions or take actions.
