    A novel linearization technique comprising thermistor-resistor-log network is shown which exhibits a linear analog temperature/voltage relation over a wide temperature range (-25°C to +110°C) with reasonably good response linearity, reliability, and overall improved performance. A notable feature of the proposed network is that the power dissipation in the thermistor is quite low and it decrease... View full abstract»

    The problem of detection and location of a small flaw inside a conducting cylinder using an eddy current coil coaxial with the cylinder has been addressed. The electric field at an arbitrary axial and radial position inside the conductor has been obtained from a previous solution of the boundary value problem. An expression for the change in complex impedance due to a small flaw located within a c... View full abstract»

    A numerical analysis of the modified Tomota-Sugiyama-Yamaguchi (TSY) time-division multiplier is compared with an extension of the analysis due to Filipski of the original TSY multiplier. Some errors and inconsistencies in a previous paper by Stabrowski are discussed. It is shown that corrections of less than 100 parts per million up to at least 2 kHz, and for any phase difference, may be achieved... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (531 KB)

    Transient capacitance studies for deep-level spectroscopy are suggested to be performed under electrical resonance conditions. Variable-frequency impedance bridges allow work at resonance, and an incremental gain for capacitance transients is obtained. This new method is presented and a few examples are discussed.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (780 KB)

    A new nonresonant method for measuring the resonance linewidth ΔH of ferrite single-crystal spheres is presented. It is based on the use of a phase-sensitive homodyne system. The analytical description of this method uses the scattering matrix description of a uniform waveguide contained in a ferrite sphere. The measurement system and a number of measurement variants have been discussed. T... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1012 KB)

    A new measuring technique of the tensor permeability of ferrite in the microwave frequencies based on Faraday rotation is proposed. A circular cylindrical waveguide containing a longitudinally magnetized ferrite rod is used. A plane polarized TE11 wave is incident upon the section where the ferrite cylinder is placed. One end of the circular waveguide is short-circuited by a movable short-circuit ... View full abstract»

    Using magnetic field data from under aerial power transmission lines, tomographic reconstruction techniques have been applied to determine the magnitudes and phases of currents in each power conductor. Phasor current values at fundamental (60 Hz) and harmonic frequencies are produced. This measurement technique requires no physical contact with power lines (even by clamp-around transformers) and h... View full abstract»

    A converter for resolving current or voltage into three mutually orthogonal components-active, reactive, and distortion-is suggested. The described system confirms the possibility of measuring the distortion current and distortion power on the basis of the time-domain approach. View full abstract»

    In the calibration of radio receivers and field-intensity meters, a radiating loop and a receiving loop under test are mainly located either in a coaxial or coplane to each other. A formula to obtain the average magnetic-field strength incident on a receiving loop is derived for the case where the radiating and receiving loop antennas have a certain deviation on a parallel plane from the coaxial o...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (575 KB)

    A simple data-acquisition system has been designed for the PC8000 microcomputer. Since the data are continually fed and stored in the 2 k bit static buffer memory in first-in-first-out order, it is possible to obtain the pretriggered data. The system can provide high sampling rates up to 50 kHz. It costs about 400 U. S. dollars. View full abstract»

    After giving a brief summary of the main devices allowing the measurement of phase shifts between two sine signals in the approximate range 1 Hz-1 GHz, we propose a new apparatus for measuring phase shift. The principle of this apparatus uses a heterodyne technique in association with a phase-locked loop which brings about frequency translation of the measured signals. The intermediate frequency w...

    A digital time-domain technique for the generation of serial minimum shift keying (SMSK) signal is described. Two pairs of synchronized antiphase sinusoidal waveforms, representing the MARK and SPACE signals, are obtained through filtering of digitally generated square waveforms. A synchronous sequential circuit then appropriately multiplexes the four sinusoids to generate the desired SMSK signal.... View full abstract»
