| abstract | This invention relates to the field of radio engineering. Increased speed. The device contains an impulse-phase detector (IFD) 1, a low-pass filter 2, a tunable rr 3, a mixer 4, a frequency divider with variable coefficients. division (DCFD) 5, digital frequency detector 6, digital integrator 7, buffer register 8, D / A converter 9, rf of reference frequency 10, frequency multiplier 11. The goal is achieved by introducing serially connected 1 down counter 12, 1 decryptor 14 , EL-OR 16, D-trigger 17, I-to-trigger 18, 2nd subtractive counter 13, 2nd decoder 15, code analyzer 19, switch 20. When changing coefficients. dividing the DCFK 5 during operation of the frequency auto-tuning ring (CPAP) sets the operating point of the IFD 1, is close to the steady-state equilibrium point of the CCAP, which eliminates repeated testing of the CVC of voltage changes at the output of the IFD 1 and sharply reduces the transient error in the ring auto-tuning, which reduces the frequency setting time and increases the speed of the device. 1 il.
