Multifunctional logical comparator for systems with phase synchronization

This article deals with expansion of functionality of a logical comparator for the systems, based on a principle of phase auto adjustment of frequency and implementing the modern methods of regulation of the output parameters. A pulse frequency-phase discriminator, which compares frequencies and phases of the two pulse sequences, is used as a basis for the construction of the multifunctional logic comparator. In addition the proposed device allows to generate the signals of indication of the operation mode of the discriminator and instants of time at which changes of the operation modes occur. The device is provided with a forced setting of the discriminator in the required operation mode. High reliability of its functioning is provided by the use of a circuit of separation of the coinciding in time pulses at the inputs of the discriminator. This circuit is realized on the basis of the trigger-distributor.
