FIELD: automatics and computer science, possible use for analog-digital transformation of sign-alternating code to frequency with possible digital correction, and also in computing devices for multiplying sequence frequency of impulse signal by parallel binary code.
SUBSTANCE: transformer (dwg.1) contains first binary multiplexer 3, transforming input sign-alternating code Nsa 18 to frequency Fy1, second binary multiplexer 6, transforming sign-alternating correcting code Ncorr to frequency Fy2, device 16 for multiplexing output signals of binary multiplexer, performing multiplexing of output frequencies of binary multiplexers 3 and 6, i.e. inserting impulses, proportional to correcting code Ncorr, into frequency-impulse stream, proportional to code Nsa being transformed.
EFFECT: realization of transformation of sign-alternating code to frequency, decreased transformation error due to introduction of digital correction of additive and multiplicative components of transformation errors.
