FIELD: technology for processing digital signals.
SUBSTANCE: in digital multi-frequency transmitter-receiver during receipt signals are simultaneously decimated and roughly converted with frequency decrease in iteration process for narrowing received broad range of frequency down to required channel, and during transmission signals are interpolated iteratively for receiving required frequency of digitization and width of frequency band.
EFFECT: provision of processing of digital signal at digitization frequency of analog-digital converter.
