Patent number: 8694273Abstract: The present invention constitutes a method, processes, and apparatus for measurement and analysis of variables of different type and origin. In particular, the invention presents a method and apparatus for real-time signal conditioning and analysis in the presense of impulsive, or sparse interferences. The present invention overcomes limitations of the prior art by providing a novel method for identifying and discriminating between, in real time, the conditions of the signal with and without impulsive disturbances. This method can be implemented without substantial changes in the signal processing chain of a communication or data acquisition system. The present invention also overcomes the shortcomings of the prior art through the introduction of the novel SPART filters, which can replace the corresponding analog linear filters in the signal chain of a device.Type: GrantFiled: November 8, 2010Date of Patent: April 8, 2014Assignee: Avatekh, Inc.Inventor: Alexei V.
