Abstract
A SMALL publication (Reference Data for Radio Engineers. Pp. 60. Standard Telephones and Cables, Ltd., 63 Aldwych, W.C.2. 2s.) should find a ready appeal to all radio engineers, whether they are engaged in replacing a small fixed resistor in a wireless receiver or a piece of laboratory apparatus, or working on the design of a world-wide radio telephone service. The data included in this booklet have been selected as a result of the experience of engineers engaged in the development of radio communication systems during the past twenty years. A very wide field is covered including electrical and mechanical constants, properties of materials, circuit theorems, impedance operators, abacs and other data of everyday utility to those conducting design and development work. A noteworthy inclusion is that of wave propagation curves summarizing the best technical knowledge available at an international conference held in 1938. The above material is supplemented by a generous amount of mathematical formulae, and the usual tabulated quantities up to and including tables of Bessel functions, the need for which has grown so rapidly of recent years in connexion with phase- and frequency-modulation systems. Since the effectiveness of any communication link, land-line or radio is nowadays expressed in terms of the ratio of the wanted signal to the noise-level, it is only natural to find a few pages devoted to noise determinationand measurement, and charts showing the relationship between the European and American units in the standardization of noise measurement. The reference book is a commendable effort in a comparatively new field.
