The analog-digital conversion equipment of the 'Orbita-RV' equipment

The analog-digital conversion (ADC) equipment of the Orbita-RV communication system serves to convert sound-broadcasting signals to digital form for transmission in standard digital bit streams over satellite or terrestrial communication links. The ADC equipment also combines standard digital bit streams into groups including printed text (newspaper) signals which are transmitted in bit streams at a rate of 2.048 Megabits/sec. The main components of the ADC equipment are a rack for transmitting radio-broadcast programs in the form of digital bit streams, a rack for the reception of these signals, a rack for routing digital bit streams, and a section for the separation of the digital bit streams. Block diagrams and the principal technical characteristics of these components are presented.
