Description
лем 2 и поступает на электрическую линию 3 задержки, где задерживаетс на врем , большее длительности импульсов электрических помех. Акустический сигнал второго канала задерживаетс акустической линией 4 задержки на врем , равное времени задержки электрической линией задержки, далее преобразуетс датчиком 5 в электрический сигнал и усиливаетс усилителем 6. Так как врем на задержки акустического сигнала в обоих каналах равно, то на выходе схемы 7 совпадени по вл етс сигнал, который поступает на вход регистратора 8. Электрическа помеха, наведенна в датчиках, кабел х или усилител х, задерживаетс только в первом приемном канале, поэтому на вход схемы совпадени сигналы поступают в разное врем , и она остаетс закрытой.Lem 2 enters the electric delay line 3, where it is delayed for a time longer than the duration of the electrical interference pulses. The acoustic signal of the second channel is delayed by the acoustic delay line 4 for the time equal to the delay time by the electric delay line, further converted by the sensor 5 into an electrical signal and amplified by the amplifier 6. Since the delay time of the acoustic signal in both channels is equal to, is the signal that is fed to the input of the recorder 8. The electrical disturbance induced in the sensors, cables or amplifiers is delayed only in the first receiving channel, therefore the input of the coincidence circuit chasing arrive at different times, and it remains closed.
Таким образом, исключаетс вли ние электрических помех на работу устройства, а также повышаетс надежность контрол качества изделий.Thus, the influence of electrical interference on the operation of the device is eliminated, and the reliability of quality control of products is also increased.
