AUTOMATIC FREQUENCY CONTROL UNIT Russian patent published in 1994 - IPC

FIELD: radio engineering. SUBSTANCE: AGC unit has counters, controlled oscillator, pulse-phase detector, code comparator, digital-to-analog and analog-to-digital converters, memory register, control signal subtracter and shaper. EFFECT: enhanced accuracy of automatic frequency control, in particular, by using the phase difference, measured at the beginning and end of the radio pulse, converted into direct voltage for correction of the control effect on the controlled oscillator. 1 dwg
