An Experimental Television System: Part II-The Transmitter

A description is given of an experimental television pick-up and transmitting installation which used a special form of cathode ray tube, the iconoscope, as the signal generating device. The installation included facilities for remote pick-up of outdoor scenes and the relaying of programs by radio. The transmitted subject matter for the tests included motion picture film, studio scenes, and outdoor scenes. Description is given of video frequency amplifiers having uniform frequency response from about 20 cycles to 600,000 cycles per second. Discussions are given on several of the problems which arose in the use of the iconoscope.
