bandwidth to a value greater than zero, the available bandwidth can be twice that of the five cabling systems.
There is a basic relationship between the channel bandwidth measured in MHz and the information transmission capability or data transmission rate measured in Mb/s. You can use the traffic flow of the main highway to visually describe the relationship between Bandwidth and data transmission rate. The bandwidth can be used as the number of lanes on the expressway, and the data transmissi
taken into account, the signal-to-noise ratio measured in decibels is the same as the cumulative power attenuation crosstalk ratio (PSACR. The goal of the six standards is to control the cumulative power attenuation crosstalk ratio (PSACR) within the frequency range of MHz bandwidth to a value greater than zero, the available bandwidth can be twice that of the five integrated wiring systems.
There is a basic relationship between the channel bandwidth measured in MHz and the information transmis
between Bandwidth and data transmission rate. The bandwidth can be used as the number of lanes on the expressway, and the data transmission rate can be used as the traffic or the number of vehicles passing through each hour. One way to expand traffic is to widen the expressway, while the other is to improve road surface quality and eliminate bottlenecks. Similarly, it is possible to enable each Hz frequency in the available bandwidth to carry more in

Morphological transformation of the image. Transform objects are generally grayscale or binary graphs, and function functions are placed within the morphology sub-module.1, expansion (dilation)Principle: Two value image is generally operated. Locate the point with a pixel value of 1 and set its neighboring pixels to this value. A value of 1 indicates white, and a value of 0 indicates black, so expansion operations can widen the range of white values a

First, CSS Div page layout When the resolution is less than or equal to 1024px (pixels), the div layout object displays 1000px width, when the resolution is greater than 1024px display 1200px width and other requirements. Use CSS to change the width of the browser display so that the layout of the page width changes dynamically (Web page width automatically with the width of the browser to widen and narrow).With the development, more and more computer

play some tricks.Two X viewportThe viewport is too narrow to display your CSS layout properly. The obvious solution is to widen the Viewport. In any case, it needs to be divided into two parts: visual viewport and layout Viewport.George Cummins the best explanation for the basic concepts on stack overflow:Think of layout viewport as a big picture that doesn't change size or shape. Now imagine that you have a smaller frame, and you look at the big pic
The dual stream uses a high bitrate code stream for local HD storage, such as QCIF/CIF/D1 encoding, where low bitrate streams are used for network transmission, such as QCIF/CIF encoding, while taking into account local storage and remote network transmission. Dual-stream can realize local transmission and remote transmission of two different bandwidth code flow needs, local transmission using high-bit stream can obtain higher HD recording storage, remote transmission using low stream to adapt t
