Where Does Static Come From

The video explains the phenomenon of static in old radios and TVs, caused by unwanted electromagnetic waves interfering with the real signal. It discusses various sources of interference, such as lightning and cosmic radiation, and how modern digital signals reduce noise by correcting slight offsets. While digital TV signals have largely replaced analog ones, analog radio is still prevalent, offering a glimpse into natural phenomena like lightning and cosmic events.

What is the cosmic microwave background radiation and its significance?

Why do modern devices experience less static compared to older devices?
