The results of the study were summarized in a peer-reviewed engineering article which discusses the theoretical basis, practical implementation and examples of potential applications for SA technology. The manuscript, submitted for review in March 2011, was published as the feature article in the IEEE Circuits and Systems Magazine, in the 3rd Qtr.

Signal Advance Technology
Signal Advance Technology Document
In recent years, a physical phenomenon referred to as Negative Group Delay (NGD), demonstrated in simple electronic circuits, has been shown to temporally advance the detection of analog waveforms. Specifically, the output is advanced in time relative to the input, as the time delay through the circuit is negative. As such, the circuit output precedes the complete detection of the input signal. We refer to this as Signal Advance (SA) technology. Success in the development and implementation of this technology has important consequences for the development of novel interventional methodologies in cardiology and neurophysiology as well as significant potential in a broader range of both medical and non-medical areas of application.
