    After comment on the obvious disparity between the print quality accepted as normal for human reading and the much higher quality needed for machine reading, a system is proposed and results of a simulation study presented for reducing this gap. The system employs a modified form of auto-correlation to extract characteristic properties from which specimen unknown characters can be identified by a ... View full abstract»

    A new thin-film metal-insulator-metal device is described. After the insulator has undergone a forming process, which consists of the electrolytic introduction of gold ions from one of the electrodes, its conductivity is observed to have increased quite markedly. In addition the sample displays negative-resistance and memory phenomena. It is shown that under the appropriate switching conditions th... View full abstract»

    Microminiature active filters have been constructed using a combination of thin film and integrated circuits. The advantages of such an approach are discussed. The filter required could be met by a fifth-order Chebyshev function and the method of realization was to split the transfer function into quadratic and linear factors with each factor then realized separately. The tolerances required have ... View full abstract»

    Thin films of In As and InSb directly evaporated on to substrates, such as glass, ceramics or ferrite, have interesting properties which make them suitable for galvanomagnetic devices as Hall probes or magneto resistors. The reasons for this are as follows: the Hall-sensitivity increases with decreasing thickness of the semiconducting layer. The higher inner resistance of thin films facilitates ma...

  • Voltage stabilized sinusoidal inverters using transistors

    Publication Year: 1967, Page(s):109 - 128

    A voltage stabilized, sinusoidal inverter system and an analysis of the operation is described. Design equations are derived for output voltage, distortion, stabilization and regulation, for loads of varying power factor. The particularly important transistor parameters are emphasized, and an inverter design example together with photographs of all relevant waveforms is included. View full abstract»

Aims & Scope

Published from 1963 to February 1964 by the British Institution of Radio Engineers and from March 1964 to 1984 by the the Institution of Electronic and Radio Engineers, The Radio and Electronic Engineer published papers describing original research and development in all branches of electronic engineering, as well as critical and interpretive surveys. Short contributions dealing with device technology, circuit techniques and experimental methods were also included.
