Abstract
An ensemble detector uses calibrated noise references to produce ensemble sets of data from which properties of non-stationary processes may be extracted. The ensemble detector comprising: a receiver; a switching device coupled to the receiver, the switching device configured to selectively connect each of a plurality of reference noise signals to the receiver; and a gain modulation circuit coupled to the receiver and configured to vary a gain of the receiver based on a forcing signal; whereby the switching device selectively connects each of the plurality of reference noise signals to the receiver to produce an output signal derived from the plurality of reference noise signals and the forcing signal.
Claims19
An ensemble detector, the ensemble detector comprising:
- a receiver;
- a switching device coupled to the receiver, the switching device configured to selectively connect each of a plurality of reference noise signals to the receiver;
- and a gain modulation circuit coupled to the receiver and configured to vary a gain of the receiver based on a forcing signal;
- whereby the switching device selectively connects each of the plurality of reference noise signals to the receiver to produce an output signal derived from the plurality of reference noise signals and the forcing signal.
A method for collecting an ensemble set of noise power measurements comprising:
- selecting a reference noise signal from a plurality of reference noise signals;
- receiving the selected reference noise signal in a receiver;
- modulating a gain of the receiver with a forcing signal to produce an output signal;
- recording the output signal to create a sample;
- and
- repeating the selecting, receiving, modulating and recording steps for each of a plurality of reference noise signals to produce an ensemble set of samples.
