Separate reprint of 5 articles published a month before in ""The Bell System Technical Journal. Four of the present articles on the early development of television were exceedingly influential, among these the paper by Frank Gray, who conducted groundbreaking research on the development of television, and Edward Nelson's important ""Radio transmission for television"". All four articles listed in ""Early Television, A Bibliographic Guide to 1940"". ""The chief problems presented in the accomplishment of television are discussed. These are: the resolution of the scene into a series of electrical signals of adequate intensity for transmission" the provision of a transmission channel capable of transmitting a wide band of frequencies without distortion means for utilizing the transmitted signals to re-create the image in a form suitable for viewing by one or more observers" arrangement for the accurate synchronization of the apparatus at the two ends of the transmission channel."" (From the introduction to the present volume).The papers contained in the present volume are:1. Ives, Herbert E. Television, pp. 1-9.2. Gray, Frank, & J. W. Horton & R. C. Mathes. The production and utilization of television signals, pp. 1-44. (ET)3. Stoller, H. M. & E. R. Morton. Synchronization of television, pp. 1-12. 4. Gannett, D. K. & E. I. Green.

First edition of the influential paper on television signals. Gray was highly influential in the development of television and conducted pioneering research in this field. ""The design of a television system, once the fundamental principles are understood, involves a detailed consideration of the methods by which the several important functions are to be performed.(1) In the present system the initial signal wave is obtained by sweeping a spot of light over the subject in parallel lines completely scanning it once every 18th of a second. The light reflected is collected by large photoelectric cells which control the transmitted current."" (From the introduction to the present paper).""A spotlight scanning method was adopted (in the present paper) to illuminate the subject, the beam of light being obtained from a 40A Sperry arc. Three photoelectric cells of the potassium hydride, gas-filled type were specially constructed and utilised to receive the reflected light from the subject. At that time they were probably the largest cells that had ever been made and presented and aperture of 120 square inches."" (Burns, R. W. Communications: an international history of the formative years, 2004, p. 497). Other papers of interest contained in the present volume:John Carson:1. Electromagnetic Theory and the Foundations of Electric Circuit Theory. Pp. 1-17.2. Propagation of Periodic Currents over a System of Parallel Wires. Pp. 495-545.E. C. Molina:1.

First edition of this classic paper on the mathematics behind the raster scan" the rectangular pattern of image capture and reconstruction in television.The mathematical theory of image scanning was developed in detail using Fourier transform techniques in the present paper. ""By the use of a two-dimensional Fourier analysis of the transmitted picture a theory of scanning is developed and the scanning system related to the signal used for the transmission. On the basis of this theory a number of conclusions can be drawn."" (From the introduction to the present paper).
