    The paper describes the operation of the multi-tanh circuit as it applies to triangle-to-sine conversion. The treatment includes a detailed examination of the properties of the transfer function of the circuit, an evaluation of total harmonic distortion with circuit parameters chosen to minimise total harmonic distortion.

  • Active-filter pole displacement due to nonideal operational amplifiers

    Publication Year: 1979, Page(s):93 - 96
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (436 KB)

    The effect of nonideal operational-amplifier output impedance on active-filter pole displacement or pole variation, respectively, is discussed and compared with the effects of finite amplifier gain and gainbandwidth product. The analysis shows that the pole variation is mainly dependent on three factors: the gain-sensitivity product, the pole frequency rated with the gain-bandwidth product, and th... View full abstract»

  • Broadband matching network design with sloped response for microwave GaAs f.e.t. amplifiers

    Publication Year: 1979
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (626 KB)

    An effective synthesis procedure is presented for the design of broadband microwave amplifiers using GaAs f.e.t.s. Based upon Youla's theory of matching, the equivalent input and output impedances of the GaAs f.e.t. are equalised to resistive source and load by lossless networks to achieve the nth order Cheby¿¿shev and Butterworth bandpass transducer power gain responses. The matching networks can... View full abstract»

  • Antenna and other systematic effects on amplitude comparison monopulse systems

    Publication Year: 1979, Page(s):103 - 108
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (551 KB)

    The paper discusses, both mathematically and systematically, a typical 4-port equispaced (over 360¿¿) antenna amplitude-comparison direction-finding system which operates over a wide microwave bandwidth. System components are examined in terms of their effect on performance and methods for reducing errors are discussed. A simple example of using a stored-calibration process is presented and it is ...

  • Time jitter in self-timed regenerative repeaters with correlated transmitted symbols

    Publication Year: 1979, Page(s):109 - 115
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (677 KB)

    This paper deals with the calculation of systematic time jitter in a self-timed regenerative repeater, where the timing circuit consists of a square-law device followed by a high-Q resonant circuit tuned to the transmission rate and a down zero-crossing detector. The method presented here can be used for any linecoding scheme and waveshape of finite duration. Some interrelations between the select... View full abstract»

  • Relationship between sensitivity and order of RC active circuits

    Publication Year: 1979, Page(s):116 - 118
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (314 KB)

    The cascade realisation of RC active filters is compared with high-order single-amplifier realisations with respect to the gain-sensitivity product. As a result it is shown that this figure of merit is proportional to nQ for cascade realisations and to Qn for single-amplifier circuits realising the same transfer function of degree 2n.

  • Idle-channel noise in p.c.m. sound-signal systems

    Publication Year: 1979, Page(s):119 - 128
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1461 KB)

    This paper describes a theoretical investigation of idle-channel noise in p.c.m. sound-signal systems and presents the results of measurements made on a high-quality (13 bits per sample linear) p.c.m. soundsignal distribution system. The amplitude probability distribution and power-density spectrum of idle-channel noise are theoretically derived, including the complication introduced when dither i... View full abstract»

  • Flexible digital correlator

    Publication Year: 1979, Page(s):129 - 133
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (560 KB)

    Development of a flexible digital correlator is described, suitable for the generation of both crossand auto-correlation functions from bandlimited signals up to 5 kHz. The resulting instrument is a 100 points, 10 kHz sampling rate, 8 bit data word correlator; it can be used in series or parallel combinations. Some preliminary data are provided on its application as a digital filter. View full abstract»

  • Implementation of a self-orthogonal convolutional code used in satellite communications

    Publication Year: 1979, Page(s):134 - 138
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (468 KB)

    A rate-7/8 self-orthogonal convolutional-code implementation is discussed. The codec uses a majority logic threshold technique for decoding the encoded data stream. The error performance of the code in a binary symmetrical channel in presence of white Gaussian noise is investigated and the input/output bit error-rate bound for the codec is computed and compared to another 7/8-rate codec that has a...

  • Computation of the moments of the time between failures for a class of repairable systems

    Publication Year: 1979, Page(s):139 - 144
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (588 KB)

    In this paper a computational algorithm is derived for the determination of the moments of the time between failures for a class of repairable systems whose components have prescribed failure distributions. Such systems are generally non-Markovian and the approach adopted here approximates system behaviour by application of the method of stages. Computation of the first moment (the mean time betwe...
