DEVICE TO GENERATE PERIODIC SEQUENCE OF SYMBOLS THAT AUTOMATICALLY ELIMINATES OCCURRING FAILURES

摘要

FIELD: measurement equipment.;SUBSTANCE: invention may be used in radio engineering devices using a shaper of periodic sequence of symbols (pseudorandom M-sequence, sequence of Gold symbols, etc.), repair of which is not possible during operation. The invention may be used to control quality of functioning of an onboard measurement system included within a scope of service instruments of spacecrafts or other radio devices. Device to generate a periodical sequence of symbols that automatically clears arising faults, comprises the following: a shaper of periodical sequence of symbols and n reserve shapers of periodical sequence of symbols, where n - integer number ≥1, at the same time each shaper of periodical sequence of symbols includes: a generator of periodic sequence of symbols; a meter of difference of a number N₁ of single and a number of N₀ zero symbols in the period of the periodical sequence of symbols; a control unit made as capable of disconnection of the shaper of periodical sequence of symbols from a source of power supply in case of a fault and connection of one of reserve shapers of the periodical sequence of symbols, which are in "unloaded" condition to the source of power supply; the secondary source of supply.;EFFECT: provision of minimum time of automatic disconnection of a shaper of a periodic sequence of symbols from a source of power supply in case of a failure, connection of a reserve shaper of periodic sequence of symbols to a source of power supply and restoration of standard operation of radio engineering equipment, repair of which during operation is not possible.;3 cl, 10 dwg
