Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

A decade-long cosmic mystery has finally been solved: astronomers have traced strange, repeating radio pulses to an unusual binary star system. The signals, detected every two hours, originate from a ...

A puzzling new type of radio signal – lasting seconds to minutes – has been linked to a binary star system featuring a white ...

This module aims to give you an understanding of basic signal and system concepts, e.g. average value, the difference between periodic, non-periodic and random signals, and orthogonality. It further ...
