The presentation title is "Robust Zero-crossing Detection in Noisy Signals Using Topological Signal Processing."
Contact Shelley Kandola (firstname.lastname@example.org) for more information.
Detecting zero-crossings in noisy signals is a classical problem that has been researched for over a century. We compare the accuracy and speed of our approach with available methods in the literature using different types of noisy signals, as well as showing sensitivity studies that consider the sampling frequency (SF), and Signal to Noise Ratio (SNR). Our results show that TSP can be directly applied to unfiltered signals with moderate to high noise levels for finding the zero-crossings. In contrast to many existing tools, our approach does not require any complex analog circuitry, iterative solvers, or filtering.
