Evaluation of Information Indicators of Quantization Noise Generated by Speech Signal Analogue-Digital Conversion

Abstract

The paper presents a technique for estimating the information parameters of the quantization noise generated by the analog-to-digital conversion of the measuring signal. An experiment and algorithm descriptions are presented to confirm the correctness of the method for processing and extracting the information parameters of the signal and quantization noise, in which a connecting cable is used instead of a measuring antenna. The measurement results are shown in the form of graphs of the dependences of the quantization noise extraction time by accumulation on influencing factors and controlled parameters, which demonstrate the limiting values of the extraction of information parameters of the quantization noise of the analog-to-digital conversion of the measuring signal. Confirmation of the hypothesis of estimating the information parameters of the quantization noise is obtained.
