  • Patent number: 8660811
    Abstract: A system for estimating bit error rates (BER) may include using a normalization factor that scales a BER to substantially normalize a Q-scale for a distribution under analysis. A normalization factor may be selected, for example, to provide a best linear fit for both right and left sides of a cumulative distribution function (CDF). In some examples, the normalized Q-scale algorithm may identify means and probabilistic amplitude(s) of Gaussian jitter contributors in the dominant extreme behavior on both sides of the distribution. For such contributors, means may be obtained from intercepts of both sides of the CDF(Qnorm(BER) with the Q(BER)=0 axis, standard deviations (sigmas) may be obtained from reciprocals of slopes of best linear fits, and amplitudes may be obtained directly from the normalization factors. In an illustrative example, a normalized Q-scale algorithm may be used to accurately predict bit error rates for sampled repeating or non-repeating data patterns.

  • Patent number: 8452559
    Abstract: A “density trace” according to an embodiment of the present invention is formed by measuring the density of each column of a frequency domain bitmap above a user-specified “amplitude threshold.” The density of each column equals the sum of the densities of all of the pixels in the column that are above the amplitude threshold divided by the sum of the densities of all of the pixels in the column. A density trace provides a convenient way to define and represent the occupancy for a large number of columns, and also allows density data to be quickly transmitted from one instrument or computer to another. In some embodiments, a density trace is incorporated into a trigger detector of a test and measurement instrument and used to generate a trigger signal. The trigger detector compares the density trace to a user-specified “density threshold” and generates the trigger signal when the value of any point of the density trace violates the density threshold.

  • Patent number: 8428911
    Abstract: A testing method for carrying out an accuracy testing operation on a system time signal of a computer device under test includes the following steps. First, first and second clock cycle parameters of an operation clock signal (CPU clock) are respectively recorded in response to first and second triggering edges triggered by an external reference time signal. Next, a reference clock cycle parameter is determined according to the first and second clock cycle parameters. Then, third and fourth clock cycle parameters of the operation clock signal are respectively recorded in response to third and fourth triggering edges triggered by the system time signal. Next, a to-be-measured clock cycle parameter is obtained according to the third and fourth clock cycle parameters. Thereafter, error information of the system time signal is obtained according to the to-be-measured clock cycle parameter and the reference clock cycle parameter.

  • Patent number: 8401819
    Abstract: Detection of one or more abnormal situations is performed using various statistical measures, such as a mean, a median, a standard deviation, etc. of one or more process parameters or variable measurements made by statistical process monitoring blocks within a plant. This detection is enhanced in various cases by using specialized data filters and data processing techniques, which are designed to be computationally simple and therefore are able to be applied to data collected at a high sampling rate in a field device having limited processing power. The enhanced data or measurements may be used to provided better or more accurate statistical measures of the data, may be used to trim the data to remove outliers from this data, may be used to fit this data to non-linear functions, or may be use to quickly detect the occurrence of various abnormal situations within specific plant equipment, such as distillation columns and fluid catalytic crackers.

    Abstract: A resistive sensor read-out apparatus is disclosed. In one embodiment, the resistive sensor read-out apparatus comprises an active sensor, a reference element, a bias circuit, a current-to-voltage converter, an analog-to-digital converter and a calibration processor. The bias circuit is coupled to the active sensor and the reference element and configured to calibrate one or more mismatches between the active sensor and the reference element. The current-to-voltage converter is coupled to an output of the bias circuit. The analog-to-digital converter is coupled to an output of the current-to-voltage converter. The calibration processor is coupled to an output of the analog-to-digital converter and configured to estimate an error caused by limited resolution mismatch calibration. The calibration processor is also configured to at least partially control calibration performed at the bias circuit based on the error.

  • Publication number: 20130018619
    Abstract: A physical quantity detection apparatus includes a signal output section, a correction value calculation section, and a processing section. The signal output section outputs signals in accordance with a change in physical quantity of a detected object. The correction value calculation section calculates a correction value. The processing section corrects values based on actual output values of the signal output section with the correction value, calculates physical quantities of the detected object based on corrected values, and outputs calculated physical quantities. The correction value calculation section calculates the correction value based on primary error amounts that are differences between post-interpolation actual output values calculated by executing a linear function interpolation process to the values based on the actual output values within a predetermined physical quantity range and the values based on the actual output values corresponding to the post-interpolation actual output values.

  • Patent number: 8352206
    Abstract: The invention describes a method that is used to determine the linearization curve of a sensor for specific gas components by combining this sensor with an ultrasonic molar mass sensor. The described method uses the fact that the molar mass sensor exhibits a completely linear response when two gas compositions of differing molar mass values are mixed. Using this feature a non linear-response of a sensor for specific gas components can be determined and a linearization curve can be computed.

  • Publication number: 20120191395
    Abstract: An intelligent electronic device, and in particular, an electrical power meter, featuring an internal calibration system capable of calibrating its measurement mechanisms for the integral nonlinearities introduced by the components which make up those mechanisms, in particular, the analog-to-digital converter, is disclosed. The analog-to-digital converter is coupled with at least one sensor which is operable to sense electrical energy in one or more conductors and output a corresponding electrical signal indicative thereof, the analog-to-digital converter being operative to convert the electrical signal output by the sensor to at least one corresponding digital signal. Integral non-linearity (“INL”) is a term describing the deviation between the ideal output of an analog-to-digital converter and the actual output (after offset and gain errors have been removed).

  • Patent number: 8228218
    Abstract: A method of reproducing an original analog signal modified by a distortion and sampled. The distortion may be linear or nonlinear, and the samples may be either ideal or non-ideal. The method determines a stationary point of a cost function based on an error vector. The method iteratively computes approximated analog signals until the approximated analog signals converge to the original analog signal. The method may utilize Fr?chet derivatives and Moore-Penrose pseudo inverse transformations in order to iteratively compute the original analog signal. An apparatus performing said method is also disclosed.
