DEVICE REGULATING THE OSCILLATIONS Russian patent published in 1994 - IPC

FIELD: test equipment. SUBSTANCE: device has series connected generator 1 of periodic signals, amplitude regulator 2, key 3, power amplifier 4, vibrator 5, vibration converter 6, matching amplifier 7, peak-value meter 8, first memory unit 9, comparator unit 10 as well as square-signal shaper 11, inverter 12, first pulse counter 13, first and second differentiating blocks, 14, 15, correspondingly, flip-flop 16. The new feature is the introduction into the device of second pulse counter 17, third pulse counter 18, second - sixth memory units 19 - 23, correspondingly, digital comparator 24, digital-to-analog converter 25, controlled repetition rate scaller 26, OR elements 30,31, delay element 32, diode 32, diode 33, commutator 34 as well as connections between them. EFFECT: enhanced functional capabilities at the expense of ensuring the possibility of programming the number of pulses in each block of amplitude values and the repetition period. 1 dwg
