His current research is focused on digital signal processing of cardiac signals, with applications for motion analysis and tracking. He currently balances his research efforts between the Center for Signal and Image Processing, the Georgia Institute of Technology, and the Department of Radiology and Imaging Sciences, Emory University School of Medicine, Atlanta.
The superscript indicates whether the specific signal is extracted by the first upper bank (A) or the second lower bank (B). Initially, an examination is performed to verify that there is no correlation between the real and imaginary part of the signal. The real/imaginary separation blocks can be expressed as simple linear relationships:
