Astronomers have pulled off an unprecedented feat: detecting ultra-faint light from the Big Bang using ground-based telescopes. This polarized light scattered by the universe's very first stars over ...

The present notebooks cover the fundamentals of linear and time-invariant signals and systems. A focus is laid on a detailed mathematical treatise. The discussion of the mathematical background is ...

The filter achieves an figure of merit (FoM) which competes with that of discrete-time (DT) filters, while avoiding the use of a clock and an antialiasing filter. Compared to prior art in CT digital ...

The focus is on the development of open- and closed-loop systems guided by real-time neuroimaging feedback, leveraging tools from control theory, signal processing ... The goal of Frontiers' ...
