FREQUENCY AUTOMATIC TUNING DIGITAL PHASE UNIT Russian patent published in 1994 - IPC

FIELD: electric communication. SUBSTANCE: in order to form step-shaped signal and application it for compensation of variable component of control signal, the device has the first and the second AND gates 12, the first and the second inverters 2, 12, OR gate 4, pulse counter 5, digital-to-analog converter 6, time detector 7, adder 8, lower frequency filter 9, clock pulse generator 10, dynamic memory unit 11, frequency divider 13, with variable division coefficient, code converter 14, reversible counter 15, control unit 16. Device provides simplification due to excluding additional equipment and to improve degree of attenuation of time fluctuations of clock pulses. EFFECT: simplification; improved degree of attenuation. 3 dwg
