FIELD: computer engineering. SUBSTANCE: device quantizes input pulse train period, its result is entered in counter, and digital-to-analog converter changes it into voltage which is then sequentially divided and multiplied by k, where k is desired coefficient of input frequency variation, and encoded in analog-to-digital converter. Code obtained is entered in counter operating as subtracter and stored in register wherefrom it is re-entered in counter during its zero filling when zero repetition rate corresponds to input frequency changed k times. EFFECT: improved design. |
