• ### The relation between picture size, viewing distance and picture quality

Publication Year: 1958, Page(s):425 - 439
Cited by:  Papers (14)
| |PDF (1918 KB)

The paper describes experiments to determine the preferred viewing distance for a number of different types and sizes of picture, including 405-line and 625-line monochrome television and a 405-line colour television picture, all with varying bandwidths. The criterion preferred viewing distanceÂ¿ proved to be surprisingly consistent and repeatable, and the results obtained indicate that, unless s... View full abstract»

• ### A pulse-and-bar waveform generator for testing television links

Publication Year: 1958, Page(s):440 - 448
Cited by:  Papers (2)
| |PDF (1199 KB)

Among the test signals used for measuring the transmission performance of television links are sine-squaredÂ¿ and `smoothed-barÂ¿ pulses. The paper gives details of the design of a test-signal generator which, at the line-frequency repetition rate, produces a composite waveform consisting of a sine-squared pulse, a smoothed-bar pulse and a normal line-synchronizing pulse. The sine-squared pulse m... View full abstract»

• ### Efficiency and reciprocity in pulse-amplitude modulation. Part 1: Principles

Publication Year: 1958, Page(s):449 - 462
Cited by:  Papers (3)
| |PDF (1809 KB)

The paper forms the first part of two papers on efficiency and reciprocity in pulse-amplitude modulation. A method of converting a low-frequency signal into a modulated pulse train and back again, with low power loss, provides multiplex communication on a 2-wire basis, without amplifiers. In principle, lossless 2-way channels with a bandwidth of half the sampling rate are feasible. The paper furni... View full abstract»

• ### Efficiency and reciprocity in pulse-amplitude modulation. Part 2: Testing and applications

Publication Year: 1958, Page(s):463 - 470
Cited by:  Papers (1)
| |PDF (1296 KB)

The paper is the second of two papers on efficiency and reciprocity in pulse-amplitude modulation, and experimental and practical aspects are discussed. Transmission with an overall loss of about 2 dB is achievable in practice and should be capable of improvement. Response is level up to about 4 kc/s using 10kc/s sampling, depending on the choice of filter. Subjective speech tests show that satisf... View full abstract»

• ### Transistor pulse generators for time-division multiplex

Publication Year: 1958, Page(s):471 - 479
| |PDF (1151 KB)

Point-contact transistor circuits to generate pulses in the microsecond range are described, together with means of frequency-dividing and interlacing pulse trains and their application to time-division operation of telephone transmission and switching systems. View full abstract»

• ### The factors influencing the use of pneumatic methods for the location of sheath faults in pressurized telephone cables

Publication Year: 1958, Page(s):483 - 486
| |PDF (605 KB)

An expression, based on the classical Poiseuille equation for gas flow through capillary tubes, has been obtained to describe the passage of gas through non-coaxial telephone cables under steady-state conditions, and, for cables in this category, the factor governing the flow has been shown to depend upon the number, gauge and arrangement of the conductors. An approximation of the pressure gradien... View full abstract»

• ### Measurement of impedance and attenuation of a cable through an arbitrary loss-free junction

Publication Year: 1958, Page(s):487 - 495
Cited by:  Papers (1)
| |PDF (1044 KB)

The paper considers the problem of finding the impedance and attenuation of a transmission line when measured through an arbitrary loss-free junction. Several possibilities for the exact determination of impedance in such a case are mentioned, and the results of tests carried out to determine the usefulness and accuracy of certain methods are presented. Some information is also given on the experi... View full abstract»

• ### Short-cut multiplication and division in automatic binary digital computers, with special reference to a new multiplication process

Publication Year: 1958, Page(s):496 - 504
Cited by:  Papers (3)
| |PDF (1427 KB)

The paper considers the application of analogues of the well-known decimal short-cut multiplication and division methods, to the control of such operations in automatic binary digital computers. After demonstrating that the simple binary short-cut process leads, on the average, to a slowing down of multiplication, the paper developes a new process, termed the modified-short-cut (m.s.c.) process.
