Abstract

The article deals with the method of increasing the dynamic range of a standard analog-to-digital converter. The method is based on interpolation of signal sections, which are limited in amplitude, using undistorted sections. Interpolation is performed by solving a system of linear equations. The error estimation and factors limiting the application of the method is made. Simulation results are presented. The conclusion is made about the prospects of using the least squares method, since in this case the interpolation error is the smallest in the mean square sense.
