1920s television system, diagram
1920s television system, diagram. This is the television system used by the Scottish engineer John Logie Baird (1888-1946), and first demonstrated in 1926. The transmitting apparatus is at left, and the receiving apparatus is at right. The system used a rotating mechanical disk with 50 holes in a spiral to break up the picture into areas to record and transmit. The information was transmitted using radio waves. At the receiver, the information is used to build up the image, which is observed through the holes of another rotating disc. Diagram published in Television (Dinsdale, 1928)
