Television by electronic methods

A number of recent advances in television methods, such as electronic scanning, receiver synchronizing via the signal channel, and light sensitive devices of great sensitivity have made possible the construction of television equipment which is thoroughly useful. Scenes with motion thus may be transmitted instantaneously, and the resulting image is stated to be almost equal in detail to good home motion pictures. The various units of a complete modern television system are discussed in this paper, with particular emphasis on the scanning, amplifying, and light translation devices. Transmission is stated to be feasible by either wire or radio.
