Description
сигнала в усилителе приемника ультразвука, выполненном на тра.нзисторах Тз-Т с выходным реле, что достигаетс посредством включени звена задержки эхо-сигнала, образуемого индуктивностью обмотки выходного реле Р усилител и подключаемого параллельно конденсатора C2i. При уменьшении эхо-сигнала ниже пороговой чувствительности приемника ток в обмотке реле Р сохран етс еще некоторое врем за счет разр да конденсатора Cai на обмотку реле. Поэтому врем отпускани реле увеличиваетс . Требуемое врем задержки эхо-сигнала будет пор дка 0,1 сек, что достигаетс подбором необходимой величины емкости €21 в соответствии с параметрами выходного реле Р. В результате задержки отпускапи выходпого реле исполнительный механизм не выключает подачуthe signal in the amplifier of the ultrasound receiver, made on the Tz-T transistors with the output relay, which is achieved by turning on the delayed echo link formed by the inductance of the winding of the output relay P of the amplifier and connected in parallel to the capacitor C2i. When the echo decreases below the threshold sensitivity of the receiver, the current in the relay coil P is maintained for some time due to the discharge of the capacitor Cai to the relay coil. Therefore, the release time of the relay is increased. The required delay time of the echo signal will be on the order of 0.1 seconds, which is achieved by selecting the required capacity value of € 21 in accordance with the parameters of the output relay P. As a result, the release delay for the output relay does not switch the actuator off
