In the process of acoustic signal processing, we often encounter the following concepts: energy spectrum, power spectrum, octave spectrum,1/3 frequency range spectrum. There are differences and links between these concepts. Some of these concepts are often mixed when people talk about problems. A little bit of time lately, I'm going to make a comb of these kinds of terms and record them here. Among them, the accurate description of the power spectral

Server virtualization technology is already helping you save money. So why not save more money? The Forrester Research Company introduced the three methods it recommended. With the global economy on the road to recovery, many enterprises urgently need to deploy new applications and start new market plans, thus increasing investment in servers. Forrester Research found that 25% of enterprises predict that server spending will increase by 5% to 10%; 6% of enterprises predict that the spending will

Most servers are configured as 24-hour running devices. Therefore, server energy-saving technologies are more important than personal products such as PCs and laptops. Generally, there are two kinds of energy-saving technologies on servers. One is energy-saving technologies for processors, such as the Power Islands technology used by IBM on Power5, Intel's SpeedS

Hot summer, most of the time we prefer to stay at home, the most enjoyable thing is to turn on the computer, watching a two movies, play a game of two games DotA ... However, friends in the summer when using computers, must remember to give love to rest and cooling time, especially the use of laptop friends, must have noticed that when watching high-definition movies or playing large 3D games, the cooling fan will run violently, and make a lot of noise, and worse, May cause a direct panic or re

People-oriented design, we must consider the ordinary people in the general task of the implementation of the tolerance problem. Because the person's energy is limited, again strong demand, powerless to complete is also in vain. The effective conversion rate of energy is the key point to measure the quality of interactive design. 1. Formula Energy generally con

See a lot of industry sites are the name of each channel to do the first page of the keyword, the more channels the more keywords on the homepage, so that the optimization of the keyword to bring great difficulty. The following to the new energy-saving supermarket as an example, to analyze the industry's key words how to optimize. Identify the core keywords for your site The first analysis of the industry, the new

IEEE has just approved the Ethernet P802.3az Energy Sensing standard, which reduces the energy consumption of networked devices while they are running. Reducing energy consumption is the next goal of information and communication technology managers in order to spend less money and work more, energy-efficient Ethernet
