gain module (gain block) provides a 5 volt DC voltage to power the low noise amplifier (LNA) inside the active antenna.A combination of a DVB TV Stick (generic P160), a low noise amplifier (LNA), and an active antenna:The GA-27 antenna to which the universal P160 DVB-T TV Stick is connected using an external LNA circuitAnother approach: Security researchers use BIAS-T networks (Standard BIAS-T Network) to connect an active GPS antenna directly to a DVB TV stick. This setting is as follows:Conne

possibility of network saturation, because the write operations are not blocked, they even return to completion state when all the data is not fully written and notify Channelfuture when this happens. You're going to risk a memory overflow and the write operation cannot be terminated, so when you write a large chunk of data, you need to be prepared to handle a case where a slow connection to a remote end produces a delay in releasing memory, and we take an example to write a file to the

P_sort = PHP % u5F00 % u53D1 % u8D44 % u6E90 % u7F51It is obvious that the urldecode () or base64_decode () of PHP cannot be reversed.Solution: Use PHP to write an anti-solution function: functionjs_unescape($str){$ret='';$len=strlen($str);for($i=0;$i{if($str[$i]=='%'$str[$i+1]=='u'){$val=hexdec(substr($str,$i+2,4));if($valelseif($

BroadcastThe transmission mode we have used so far is called "single point Propagation", and the definition of single point propagation is that the message is sent only to a network destination confirmed by a unique address, which can be supported by two protocols with links and no connections, and UDP provides additional transport modes for sending messages to multiple recipients1) Multicast (multicast)----------transferred to a defined set of terminals2) Broadcast (broadcast)--------------tra

Basic knowledge of the network:The concept of the network Network is node weighted graph Network In addition to the mathematical definition, there are specific physical meanings, that is, that the network is a model abstracted from an actual problem of the same kind.
