Why Do We Need To Know About Digital Signal
Learning about digital signals helps us understand how things like phones, the internet, and storing information work. Digital signals use a series of ones and zeros, which helps messages travel far without losing quality. This is why we can explore space, listen to clear music, and use GPS accurately.
These signals are also why our smartphones and Wi-Fi are so good at keeping us connected. In the world of making software, digital signals are important because they help build and keep up all the apps and websites we use, leading to lots of jobs.
