In this work, we study the problems of processing complex-nature signals subject to noise, which arise because of the insufficient dynamic range of these signals in the case of their digital representation. The information criteria of quantization of the complex-signal amplitude are considered. The information-analytical approach to solving the problem of coding the signal amplitudes, which is aimed at retrieving the maximum amount of information for the minimum volume of the obtained code, is formulated. Particular results of using such an approach are given.
