SU444130A1 - Harmonic Error Coding Device - Google Patents

Description

The invention relates to a phase-measuring technique and can be used to create phase information conversion and coding devices. The known phase-shifting devices with harmonic error compensation, containing a counter, the gene & Rotor, keys, and two chains consisting of pulse shapers and coincidence circuits have a low accuracy, limited by the frequency range, and do not provide for the maximum implementation of single channel coding. The purpose of the invention is to improve coding accuracy, to expand the frequency range of input signals and to provide single-channel coding capability. and match schemes. The drawing shows the block diagram of the proposed device. It contains generator I, counter 2, key 3, pulse shapers 4 and 5, coincidence circuits 6 and 7, memory register 8, digital-to-analog converter 9, adder 10, additional driver II, additional coincidence circuit 12, key 13, additional counter 14 and .ara ftvticheskbv device 15, the device operates as follows. When a quasi-harmonic signal arrives at the input, pulse shaper 4 generates a pulse according to the sign of the transition from minus to positive, the coincidence circuit 6 opens key 3 and the regenerator I pulses are passed to counter 2. The pulse impulse 5 generates pulses according to the sign of the transition from positive to minus, when the etch scheme is the same, day 7, the G is triggered, the key is 3; This code determines the level of constant voltage that is output from the digital-to-analog converter.

9 is fed to adder 10, where it is summed with the input voltage. Pulse generator II generates a sequence of pulses, which matches the matching circuit 12, opening the key 13 and skipping the generator I pulses to the counter 14, which counts the pulses until the time fixed by the circuit is the same, value 6 closing the key 13. Counts from counters 2 and 14 are sent to an arithmetic unit 15, at the output of which an error code is obtained.
