A Binarizing NUV Prior and its Use for M-Level Control and Digital-to-Analog Conversion
Raphael Keusch, Hans-Andrea Loeliger
Priors with a NUV representation (normal with unknown variance) have mostly been used for sparsity. In this paper, a novel NUV prior is proposed that effectively binarizes. While s…
Binary Control and Digital-to-Analog Conversion Using Composite NUV Priors and Iterative Gaussian Message Passing
Raphael Keusch, Hampus Malmberg, Hans-Andrea Loeliger
The paper proposes a new method to determine a binary control signal for an analog linear system such that the state, or some output, of the system follows a given target trajector…
Control-Bounded Analog-to-Digital Conversion: Transfer Function Analysis, Proof of Concept, and Digital Filter Implementation
Hans-Andrea Loeliger, Hampus Malmberg, Georg Wilckens
Control-bounded analog-to-digital conversion has many commonalities with delta-sigma conversion, but it can profitably use more general analog filters. The paper describes the oper…
