• ### Differences of opinion about dimensions

Publication Year: 1957, Page(s):198 - 205
| | PDF (1305 KB)

Contemporary differences of opinion among leading authorities about dimensions are numerous and often extreme. It is sometimes overlooked that the use made of the theory of dimensions is purely algebraic, and mistakes in elementary algebra are the cause of several of the more extreme opinions. When these have been excluded, it is shown that dimensional quantity appears as a synonym for independent... View full abstract»

Publication Year: 1957, Page(s):210 - 212
| | PDF (287 KB)

A series of v.h.f. measurements over long sea paths was made over a period of 15 months. The results suggest that, in general, higher field strengths are reached for a given percentage of the overall time than in the case of over-land paths. View full abstract»

• ### The B.B.C. sound broadcasting service on very high frequencies

Publication Year: 1957, Page(s):213 - 224
| | PDF (1881 KB)

The paper describes the developments leading to the inauguration of the B.B.C. very-high-frequency service of sound broadcasting, which works in the band 87.5Â¿100Mc/s. The need for a very-high-frequency service is explained, and the considerations leading to the choice of frequency modulation rather than amplitude modulation, and of the national planning standards, are summarized. In July, 1954, ... View full abstract»

Equipment and performance requirements for frequency-modulated broadcasting transmission are given, with particular reference to the British Broadcasting Corporation's recently introduced network of v.h.f. transmitters. The general planning and design of the complete transmitting equipment used at the new high-power v.h.f. sites is surveyed, including problems of unattended operation, automatic ph...

Publication Year: 1957, Page(s):239 - 249

| | PDF (1542 KB)

An f.m. system is described which employs a directly-frequency-modulated quartz-crystal oscillator, the design of the circuit and of the crystal plate being treated in some detail. Easy methods of setting-up derive from the use of an oscillator having a high Q-factor. The system has the advantages of simplicity, reliability and ease of maintenance. View full abstract»

Cited by:  Papers (1)
| | PDF (1101 KB)

Tubular metal waveguides of circular cross-section supporting the H01-mode and operated at a frequency well above the cut-off value for the guide are known to be capable, in ideal circumstances, of providing a screened microwave channel having an attenuation of only a few decibels per mile. The paper is concerned with the practicability of this arrangement at a frequency of 35 Gc/s employing strai... View full abstract»

• ### A new form of hybrid junction for microwave frequencies

| | PDF (523 KB)

The principle of the branch-waveguide directional coupler has been applied to the design of a new form of hybrid junction for microwave frequencies. An equal division of power between the main and subsidiary waveguides is achieved by arranging the voltage coupling coefficients of the branch waveguides in accordance with the coefficients in a binomial expansion. Details of design and performance of... View full abstract»

| | PDF (1364 KB)

Two sets of data are fundamentally required to describe a television picture, one giving the significant changes of brightness, and the other the positions of such changes. The total information content is calculated according to Shannon, and the means are discussed for reducing bandwidth by redistributing the data in time so as to achieve a constant rate of transmission. Maximum compression is ac... View full abstract»

• ### A theoretical and experimental investigation of anisotropic-dielectric-loaded linear electron accelerators

| | PDF (2456 KB)

The general properties of linear accelerator waveguides loaded with spaced discs of ceramic dielectric are investigated theoretically and these waveguides are shown to have a higher shunt impedance than all-metal waveguides. Theoretical and experimental methods of waveguide design follow, a combination of which is used to design an experimental linear electron accelerator. Early experience with th... View full abstract»

Publication Year: 1957, Page(s):293 - 306
Cited by:  Papers (1)
| | PDF (1852 KB)

Junction-transistor linear-sweep circuits of the bootstrapÂ¿ type are described for which deviations from perfect sweep linearity of much less than 1% are estimated to be possible. The operation of the circuits depends on the properties of the emitter-follower amplifier stage; these properties are shown to be very well suited for such applications. The basic bootstrap circuit is closely related t... View full abstract»

| | PDF (1127 KB)

Resonant oscillators using transistors provide a suitable means for the conversion of d.c. into a.c. power, in particular where a reasonably sinusoidal output voltage is required. For the design of such oscillators, the current-amplification factor, the fraction of the cycle during which collector current is permitted to flow and the feedback conditions have to be considered. The maintenance equat... View full abstract»

• ### Minority-carrier storage in semi-conductor diodes

Publication Year: 1957, Page(s):318 - 332
| | PDF (1941 KB)

Hole storage is an effect which takes place in semi-conductor valves using n-type base material; it has a counterpart in electron storage in p-type material. It gives rise to several electrical effects, particularly to transient reverse currents in diodes on the application of a reverse bias. The effects are deduced, quantitatively, by solving the continuity equation with boundary conditions appro... View full abstract»

• ### A new method for the detection of thin conducting films in thermionic valves

Publication Year: 1957, Page(s):337 - 340
| | PDF (585 KB)

A method has been devised for the detection of thin conducting films on insulating surfaces, but its application has so far been restricted to the detection of films in thermionic valves, for which it is particularly suitable. Known as the triple-band methodÂ¿, it is simple, does not call for special valve constructions and requires only normal laboratory equipment. While the method was developed... View full abstract»
