Zusammenfassung:	FIELD: measuring technology prestart monitoring of frequency. SUBSTANCE: device includes pulse shaper 1, counter 2, flip-flops 3, 4, 5, univibrators employing Shmitt flip-flops 6 and 7 and 2 NAND gate 8. EFFECT: enhanced accuracy of monitoring signals due to comparison of duration of pulses of univibrators with total duration of several periods of input signal whose number is determined by means of counter. 2 dwg
