    In this paper, a principle for absolute voltage division is presented. The division ratio of a voltage divider on this principle does not depend on the values of its elements but depends exclusively on the configuration of the divider network. Hence, calibration is not necessary and not even possible. Absolute voltage division is obtained by cyclically shifting the network elements along all posit... View full abstract»

    A substantial discrepancy was found to exist between the sigma (standard deviation) of the noise present in radar data as determined by subtraction of data smoothed by a low-pass filter from the raw data and use of successive differences to isolate the noise. An investigation revealed that implicit in the equation based on the successive differences approach was the assumption that the noise was w... View full abstract»

    The phase-locked loop (PLL) is applied to generating and measuring large phase jitter that can be encountered in digital transmission systems. It is shown that jitter can be generated and measured by a PLL operated as a phase modulator and phase demodulator, respectively. Equations and examples are given for practical PLL designs to generate and measure jitter of a certain amplitude range and band... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1005 KB)

    A theoretical model is developed for a pendulum-variable inductance ac RL bridge type velocity gauge. Lagrange's equations and an extension of a solution to a restricted form of Navier-Stokes' equations are used to develop the mechanical-fluidic portion of the model. Ampere's circuital law and Kirchhoff's laws are the basis for the magnetic-electrical portion of the model. State variables are defi... View full abstract»

    Electrode surface effects in parallel-plate capacitors lead to a variation in capacitance and conductance with frequency. A method is presented for the determination of absolute changes in capacitance and absolute values of conductance, as functions of frequency. The method involves the use of two variable parallel-plate capacitors, and requires the measurement of relative capacitance and conducta... View full abstract»

    This paper describes a new solid state circuit for resistance measurement in the range 1-108 Ω. The advantages of this circuit include: reliability, simplicity of design and use, low cost, and the fact that resistance scale is linear. The accuracy of measurement is around ±2 percent of reading at full-scale value in the range 1-106 Ω and ±6 percent of reading at 10 M�... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (641 KB)

    This paper presents two types of active configurations for realizing electronically tunable RC sinusoidal oscillators. The type-1 network employs two grounded scaled resistances KR1 and KR2, where K is a scaling factor. The frequency of oscillation Wo is controlled conveniently by adjusting K, since Wo appears in the form W0 = l/K/√R1C1R2C2. For realizing the scaled resistances, an active ... View full abstract»

    Cosmic background noise temperature measurements which were made at 13.05-cm wavelength (2297 MHz) resulted in an experimental value of [266 ± 0.77 (3σ)] K. The two largest error sources were due to uncertainties in the calibration of the liquid helium cooled termination and the antenna transmission line. The 2.66 K value is in good agreement with the currently accepted value of 2.8 K... View full abstract»

    A unique method for the continuous measurement of electric-arc duration is presented. By using the method, it is possible to know the distribution of arc durations at any instance of time and, at the same time, the integration of arc durations has become much more convenient and less time consuming than any other existing methods. It has also been found that the total integrated-arc durations bear... View full abstract»
