交换机及路由器工作原理(Switch and router working principle).doc,交换机及路由器工作原理(Switch and router working principle) 1. Overview Switching technology is a kind of switching product with simplified, low cost, high performance and high port dens
Laser cutting machineis now the most advanced mechanical processing equipment, laser is first used in the field of mechanical processing, brought unprecedented promotion to the development of mechanical processing. What is the working principle oflaser cutting machine? A lot of people to the laser c...
Optical fibres are insensitive to magnetic fields of any kind. Since they are based on a different physical principle than power cables, fibre optic cables require neither earthing nor galvanic isolation. They do not conduct electricity and connot caus...
the working principle of photovoltaic cells, important performance parameters, different generations based on different semiconductor material systems and fabrication techniques, special PV cell types such as multi-junction and bifacial cells, and various technical details such as surface passivation and text...
Working Principle Avalanche breakdown occurs mainly once thephotodiodeis subjected to maximum reverse voltage. This voltage enhances the electric field beyond the depletion layer. When incident light penetrates the p+ region then it gets absorbed within the extremely resistive p region then electron-hole...
while the power electronic converters are combined to achieve active control. Equivalent magnetic and electrical circuit models are established to help discuss the operating principle of the proposed HPR. Additionally, the power flow and control principle of the HPR in different operating conditions are...
The term transceiver is not a separate network device but it is integrated intoa networkcard device. As the name suggests, it is a combination of a transmitter as well as a receiver of signals, like analog (or) digital. In principle, the transceiver on a LAN is responsible to situate sig...
Ⅳ LCD working principle Ⅰ LCD Features (1) Low-voltage and micropower consumption (2) The appearance is small and exquisite, the thickness is only 6.5~8mm (3) Passive display type (no glare, no irritation to human eyes, and no eye fatigue) (4) The amount of display information is lar...
