Recovery of Signals Encoded by Sample-and-Hold Asynchronous Sigma-Delta Modulation

Abstract

The paper is focused on methods of the perfect signal recovery based on the frame theory, and the approximate fast reconstruction with truncated Fourier series for inputs encoded by Sample-and-Hold Asynchronous Sigma Delta Modulation (SH-ASDM). The comparative analysis shows that the signal recovery for the SH-ASDM is characterized by significantly lower computational complexity than for the classical ASDM.
