Abstract :
Television equipment, in particular that supplied to the B.B.C. for the London Television Station, is described, and the technical considerations which led to its development are outlined. A description is given of the purpose and practical design of the apparatus handling modulation frequencies, which comprises studio equipment, camera control equipment, modulation amplifiers for the radio transmitter, and associated apparatus. Owing to the large amount of equipment covered by these headings, little more than cursory descriptions can be included, making it imperative to omit many details of design. References are therefore made to the relevant patent specifications, from which more detailed information may be gathered.
