Compensation of Errors in Multi-Channel Analog-to-Digital Convertors at Signal Processing of Multidimensional Arrays

Abstract

Sources of the errors and compensating methods at multi-channel analogto-digital convertor (ADC), in which an output signal is a many-dimensional array or set of the one-dimensional arrays, are considered. The source of the error in the common sample-and-hold (SH) circuit of the modern ADC for several channels is analyzed. Methods of errors compensation in time and frequency domains for the algorithm of geometrical coordinates of a signal source determining are analyzed.
