PLL principle && clock generation method for phase-locked loop

The PLL is an abbreviation for the phase-locked Loop, and the Chinese meaning is a phase-locked loop. The PLL is essentially a closed-loop feedback control system that allows the PLL output to maintain a fixed phase relationship with a reference signal. The PLL is typically composed of a phase detector, a charge amplifier (Charge Pump), a low-pass filter, a voltage-controlled oscillator (electrical), and some form of output converter. To make the PLL'

Progress of optoelectronic devices in automatic switched optical networks

compared with the discrete component system, which greatly reduces the volume and reduces the cost of the package. In the development of miniaturized optical devices, laser/detector devices and microelectronic chips are assembled into one, and the development trend of forming a variety of functional modules is obviously accelerated. Modularization can eliminate parasitic parameters to improve performance, and can save the process and cost of post ass

ILSVRC2016 Target Detection Task review-video target detection (VID)

Original URL: Http://www.cnblogs.com/laiqun/p/6501865.html The task of image target detection has made great progress in the past three years, and the detection performance has been significantly improved. But in video surveillance, vehicle-assisted driving and other fields, video-based target detection has a wider range of needs. Because of the problems such as motion blur, occlusion, diversity of morphological variation and diversity of illumination, it is not possible to detect the target i

He should be strong and consistent, that is, even in the event of a communication failure, all nodes in the system should have a consistent view (that is, all nodes should know which nodes are unavailable, those nodes are available, each node cognition of this can not conflict, not a part of the node know that a node A is not available , while t

You must also ask "agents" such as "Fearless Bound File Detector" to clear the Trojan.After the program runs, you must first select the program or File to be checked, and then click the "Process" button on the main interface. After the analysis is complete, click the "Clean File" button, in the displayed warning dialog box, click "yes" to confirm that the trojan i

to provide unlimited access to the network and obtain key data through spoofing. Without knowing it, the wireless LAN User thought that he was connected to the wireless LAN through a good signal, but he was not aware that he had been listened to by hackers. With the low cost and ease of configuration, wireless LAN is becoming increasingly popular. Many users can also set up wireless base stations (WAPS) in their traditional LAN ), the backdoor programs installed by some users on the network als
