Baird's system of television transmission

Baird's system of television transmission, developed by John Logie Baird in the 1920s, used a mechanical process called a Nipkow disk to scan and create images. The disk had many tiny holes that rotated to scan an image line by line, converting it into electrical signals. These signals were then transmitted wirelessly using radio waves to a receiver with a similar disk that reconstructed the image. While innovative for its time, Baird's system was limited in picture quality and resolution, paving the way for later electronic television systems that used cathode ray tubes and electronic scanning techniques.
