| 摘要 |
The device is applied in the field of radio engineering and is characterised by reduced probability for false alarms. It consists of: first threshold circuit (1), the information input of the latter is input of the device, second threshold circuit (2), first delay line (3), first restriction circuit (4), first provisional quantum element (5), second restriction circuit (6), first reversible counter (7), first D/A converter (8), DC amplifier, first selector of pulses according to duration (10), third restricting circuit (11), first generator of reference pulses (12), fourth restriction circuit (13), second provisional quantum element (14), frequency divider (15), fifth restriction circuit (16), first decoder restricting overflow (17) decoder restricting zeroing (18), second selector of pulses according to duration (19), second delay line (20), third provisional quantum element (21), sixth restriction circuit (22), seventh restriction circuit (23) second reversible counter (24), second D/A converter (25), eighth restriction circuit (26), ninth restriction circuit (27), second overflow restricting decoder (28), second decoder restricting zeroing (29), tenth restriction circuit (30), second generator of reference pulses (31), and the output of the third provisional quantum element (21) is the output of the device.
