DEVICE FOR TRANSMISSION OF RADIO TELEMETERING SIGNALS Russian patent published in 1999 - IPC

FIELD: continuous and simultaneous tests of great number of various parameters. SUBSTANCE: device for transmission of radio telemetering signals has receiver, analog-to-digital converter, unit of keys, first switch, command decoder, shift register, second switch, synchronizer of telemetering format, 2AND gates, first and second univibrators, generator of pseudorandom sequence, flip-flop, counter, AND gate, OR- ELSE gate, error counter, comparator, retunable generator, distributor, former, amplifier of supply pulses, commutator, measurement bridges, OR gate, adders, analog-to-digital converters, code converter, low frequency filter, modulator, former of synchropulses, radio transmitter. Operation of device is based on bit by bit comparison by second OR-ELSE gate of binary number known a priori and stored in registers of generator of pseudorandom sequence with copy of this signal reconstructed with adjustable level of regeneration and phased to accuracy of one bit. Change of frequency of clock generator, that is of data transmission speed, is conducted by comparison results. EFFECT: improved functional efficiency of device. 2 dwg
