radio engineering; digital data transmission systems. SUBSTANCE: device has shift register 1, current phase decoder 2 built around current-phase read-only memory 9 and adder 10, digital- to-analog generator 4, initial phase decoder 5 built around initial phase read-only memory 11 and adder 12, initial-phase random-access memory 6, clock space counter 7, and frequency synthesizer 7. Proposed device provides for timing sequential conversion of shaped signal samples with boundaries of clock and character intervals. EFFECT: enhanced precision of continuously phase modulated radio signal being shaped. 3 cl, 4 dwg |
