System and method to estimate signal artifacts
First Claim
Patent Images
1. A device comprising:
- a controller;
a memory coupled to the controller; and
an input interface arranged to received at least two event signals, wherein the controller is arranged to determine an estimated value of at least one of the at least two event signals using a transform function and at least the other of the at least two event signals, and to determine a deviation between the estimated event signal and the at leat one event signal, and to determine whether an artifact is present in the at least one event signal in accordance with the deviation.

Abstract
A method and system are disclosed that detect signal artifacts in one or more event signals. The system and method may be used to estimate whether a monitored signal includes artifacts based upon a statistical analysis using a transform function.

7. A method for detecting a signal artifact in an event signal, the method comprising the steps of:
-
receiving at least two event signals;
determining an estimated value of at least one of the at least two event signals using a transform function and at least the other of the at least two event signals;
determining a deviation between the estimated event signal and the at leat one event signal; and
determining whether an artifact is present in the at least one event signal in accordance with the deviation. - View Dependent Claims (11, 12)
