The Marconi-E.M.I. television system. Part 1: The transmitted wave-form

This part of the paper describes the technical considerations leading to the choice of the particular wave-form now standardized by the B.B.C. for radiation from the London Television Station. The various characteristics of the system are described, together with the considerations that led to their adoption. A slight modification of the published wave-form specification is suggested. Finally, automatic volume control is briefly discussed. An appendix gives the modified wave-form specification.
