Without Fourier & Co: An alternative Pattern Detection and Signal Filtering Method Using the Example of Biosignals

We got used to the thinking and the analysis of signals in the frequency domain and to design analog or digital filters accordingly. Methods such as Fourier transforms, IIR and FIR filters are among the basic tools of every engineer. Nonetheless, in particular biological signals are often of pulse-like nature and, thus, easier to describe in the time domain. This presentation discusses a model-based analysis and filtering method in the time domain which allows to perform efficient pattern detection, signal filtering, and signal decomposition. In particular, an intuitive approach to this method is offered with examples from the field of cardiology (ECG signals).


Dr. Reto Wildhaber PhD Student BFH, Institute for Human Centered Engineering, HuCE / ETH Zürich, Signal and Information Processing Laboratory ISI

Reto Wildhaber has been employed at the Bern University of Applied Science in Biel since 2013 and is doing research in the field of esophageal electrocardiography. He is currently also working toward the Ph.D. degree at the Department of Information Technology and Electrical Engineering at the ETH Zurich. After his degree in electrical engineering from the University of Applied Science in Rapperswil in 2002, he was employed in R&D of a mid-size company until 2006. Following this, he started his studies in human medicine and received the M.D. (Dr. med.) degree from the University of Zurich in 2014.

This Seminar is held in collaboration with the IEEE association.
