Метод аналого-цифрового перетворення телевізійних сигналів з надмірною дискретизацією

Abstract

In this master's qualification work research of analog-digital converter is conducted for the digital system of transferrableness of televisional signals. The paper considers the appointment, the problem that has arisen and solutions to the latter, and the analysis methods for the study of the problem. In master's qualification work development of method of increase of zavadostiykosti and decline of complication of realization of analog-digital converters is conducted for the digital system of transferrableness of televisional signals. Done developing analog-digital converter (ADC) based on differential pulse-code modulation signal channels with high sampling rates. The analysis parameters built ADC television signals. The calculations of economic costs of research and feasibility of investment in this unit. The questions of life safety device in the study and calculation of parameters of protection against electromagnetic radiation. The analysis of the received results is made.
