5 Pulses of the carrier frequency of the source, the reference voltage 1 are fed to block 5, the output of which is connected to filter 7, which separates the difference frequency 3 2 Frequency, is fed from the output of the filter to block 6. At the output of block 6 4, the total frequency is equal to Frequencies i are obtained from frequency f by dividing "ah in Frequency Divider (Pulses) 2 and Frequency Divider 3. The frequency 1 obtained at the output of the filter S is fed to a splitter 9, allowing four quadrature oscillations (shifted by 90) to be obtained. In this case, the frequency divider 2 serves to obtain the frequency / C by which the frequency f is lowered. in block 5, and the control unit 4 is to receive the phase fluctuation jE at the output of frequency divider 3 by adding or excluding pulses at its input. The law of distribution of carrier phase fluctuations is modeled on the digital computer. The information from the carrier is fed to the memory 10. The coded value of the process increment written into the memory cell is converted by the code-11 converter into a sequence of pulses, the number of which corresponds to the code. Pulses from the output of the converter code-number are sent to the control unit 4, where frequency f applied from the source of the reference voltage 1 to the input of the frequency divider h is added to the sequence of pulses, or prohibited, depending on the sign of the increment recorded on the carrier. The phase of the frequency | n at the output of the frequency divider varies by the interval At in accordance with the increment information received from the carrier.
