    This paper shows analytically that the distance exponent, n, obtained by comparing power levels at two points beyond radio horizon depends upon (i) the region beyond horizon where these points are located (diffraction or forward scatter region), (ii) the relative positions of these points, (iii) the initial gradient of refractivity and (iv) heights of the antenna terminals. In the diffraction regi... View full abstract»

    The function-generating requirements in an existing design of `pipe cell¿, which simulates the hydraulic behaviour of pipes, are reviewed and a simpler method of meeting them is explained. A cell design embodying the new approach is described. View full abstract»

    An expression, involving the degree of mismatch in the respective parameters of similar integrated circuit components, operated at similar current levels, is presented for the error limits of a new voltage-ratio-circuit having a small source loading and a low output resistance. Using currently available s.i.c. process technology, an output error <1% is readily achieved. Experimental results wit... View full abstract»

    When considering the design of receivers for direct broadcasting of f.m. television from satellites at 12 GHz, a common requirement in all variations is for a local oscillator which supplies several milliwatts of power at approximately 11.7 GHz. A specification is derived for the maximum allowable noise on the local oscillator when the device used is an avalanche diode oscillator or a Gunn effect ... View full abstract»

    In domestic, commercial, light industrial, and some recreational environments, there exists a requirement for the economical detection of potentially explosive concentrations of inflammable gases. The recently introduced Taguchi gas sensor, or T.G.S., is an inexpensive semiconductor transducer which is sensitive to all inflammable gases, and has electrical characteristics which appear to make it s...

    Generalized duals and generalized inverses are defined for any general network N consisting of linear/nonlinear, time-invariant/time-varying, passive/active, lumped/distributed elements. A simple method of obtaining these directly for a general planar three terminal network is given. Applications of these concepts in network synthesis are discussed. View full abstract»
