Statistical determination of power-circuit connectivity

摘要

A mechanism is provided for statistical determination of power circuit connectivity based on signal detection in a circuit. Signal data from the circuit gathered and a determination is made as to whether a signal of interest is present in the gathered signal data from the circuit using a statistical analysis of the gathered signal data. The statistical analysis comprises using a mean current value and statistical deviation of the current value of the signal data over a predetermined period of time to compute a confidence range. The confidence range is compared to a first threshold and a second threshold. A determination is made that the signal is present in response to the confidence range being above the first threshold. A determination is made that the signal is not present in response to the confidence range being below the second threshold.

1. A method, in a data processing system, for statistical determination of power circuit connectivity based on signal detection in a circuit, comprising:
gathering signal data from the circuit; and determining whether a signal of interest is present in the gathered signal data from the circuit using a statistical analysis of the gathered signal data, wherein the statistical analysis comprises using a mean current value and statistical deviation of the current value of the signal data over a predetermined period of time to compute a confidence range and comparing the confidence range to a first threshold and a second threshold, wherein a determination that the signal is present is made in response to the confidence range being above the first threshold, and wherein a determination that the signal is not present is made in response to the confidence range being below the second threshold.
