Xsampling (Sub-Nyquist sampling)

Xampling is a system architecture designed for sampling and processing of analog inputs at rates far below the Nyquist rate, whose underlying structure can be modeled as a union of subspaces. This website provides a brief  introduction to union modeling and the Xampling framework, through several examples of engineering applications.
