The aim of the article is to examine the issue of eliminating quantization noise in the process of analogue-to-digital conversion by means of timing pulse code modulation. According to the results of the method proposed, it has established that the use of timing modulation significantly increases the number of sampling levels at a given interval without reducing the duration of individual code pulses, that, in its turn, significantly improves signal quality (readability) after the digital-to-analogue conversion on the receiving side.
