Increasing ADC dynamic range in information-measuring systems by methods of digital signal processing
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. Th...

| Summary: | 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. |
