  • Estimating Unbiased Average Power of Digital Signal in the Presence of High-Level Impulses

    Publication Year: 1983, Page(s):403 - 409

    Signaling data collected in the mobile radio field environment have revealed an extremely high value of impulsive noise contamination. When the sampled data contain such high-level impulses, the impulses tend to dominate the average value calculations and could result in mean values which may not be representative of the noise power which affects the system performance (signaling and voice). A sta... View full abstract»

    In this paper, we report the results of an experimental study of the short-and mid-term frequency stability for both a hydrogen maser and a rubidium maser operated with an external feedback loop to modify the cavity quality factor. A revised version of the theoretical expression of the frequency stability for this type of maser is given and a numerical solution for various maser parameters is calc... View full abstract»

    A precipitation instrumentation package for sensing rainfall intensity with fine time and space resolution is described. The package comprises a drop-counter precipitation sensor, a microcomputer-based data-acquisition system, and an intelligent data decoder. A comparison is made between the precipitation sensor and the conventional tipping bucket rain gauge, and the merits of the new system are d... View full abstract»

    The harmonic mixing performance due to hot carrier diodes utilizing high field effects in semiconductors has been investigated. Model experiments in the 35-GHz band have been performed to obtain the optimum structure and NEP (Noise Equivalent Power). NEP of 2 × 10-11 W/5-MHz for a 3rd-order harmonic mixer was obtained.

    This paper describes a microcomputer-controlled measurement system for continuous measurement of the density of a streaming liquid. The system utilizes a transducer that resembles a hollow tuning fork filled with liquid. The resonant frequency of the fundamental mode of this device is a function of the liquid density. Piezoelectric means are used to force the device to oscillate and to register th... View full abstract»

    Fast correlation calculations are needed in many technological and scientific fields. Conventional digital correlators require fast and expensive analog-to-digital converters and digital multipliers. This paper describes the implementation of a fast, inexpensive, and unbiased correlation estimator. The estimator is based on the ternary Random Reference Correlation (RRC). Unbiasness is achieved by ... View full abstract»

  • Impossibility of Linear Two-Port Noise-Parameter Measurement with a Single Temperature Noise Source

    Publication Year: 1983, Page(s):443 - 445
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (891 KB)

    The noise parameters of a linear two-port are usually evaluated through four measurements of the noise figure of the two-port, and the noise figure is in turn determined through the measurements of the noise power output of the two-port when a noise source is connected at its input. It is shown that if the noise power output is the only measured quantity, then the noise parameters cannot be calcul... View full abstract»

    A major step in the precise determination of the quantized Hall resistance is the comparison of a resistor of value nominally 6453.2 Ω with a 1-Ω standard. For this purpose the National Measurement Laboratory will use a build-up resistor comprising 83 resistors each of 801/3 Ω, giving a ratio of 64534/9. An accuracy of better than 1 in 108 is expected.

    Two new methods using the concepts of cross correlation and cross variance are proposed for comparing three oscillators. They allow one to characterize individually each oscillator and they reduce the influence of the measurement system noise if the noise sources on each channel are independent. Therefore, better resolution can be obtained in the spectral purity and frequency stability measurement... View full abstract»

    An intermediate frequency substitution method in the optical region is studied experimentally for attenuation measurement of laser beams. A frequency shifting technique with an acoustooptic modulator is used to obtain test and local oscillator signals for heterodyne detection.
