optical delay circuit 中文意思是什麼
optical delay circuit
解釋
光學延遲迴路-
On the one hand, the receiver must be self - adaptive to set as fast as possible the " 0 " and " 1 " bit level judgement threshold in a dynamic way ; on the other hand, the transmitter of onu should take some measures to minimize and compensate for the burst delay. the optical burst transmission circuit is thus required to switch on and off the laser in a snappy way to ensure fast signal sending. in that sense, the laser must be designed with a superb response speed
一方面，接收機必須具有自適應功能，能以最快的速度動態調定" 0 " 、 " 1 "比特電平判決門限；另一方面， onu的發射機應該採取-定的措施減小和補償突發時延，其光突發發送電路要求能夠非常快速地開啟和關斷激光器，迅速發送信號，所以，它需要使用響應速度很快的激光器。 -
Based on studying of the multi - level technique, a variable frequency speed regulation system based on the diode clamped three - level inverter is introduced in this thesis in detail. it includes ac - dc - ac main power circuit, snubber circuit, isolated driving circuit by optical fibre, delay time circuit on powering, sampling circuit of current and voltage, protection circuit and etc. a distributed power system ( dps ) which can reinforced the system ’ s security is developed to solve the power supply of the whole system
