TD62382AF Article About

In 1992, Deng Xiaopings southern tour speech, certainly a market economy, gave birth to a market economy boom. Since then, Chinas entrepreneurs have. The growth of emerging companies group full of enthusiasm, excellent management concepts and practices needed guidance. "World Executive" magazine came into being. It the worlds leading management thinking and practice into China, is committed to promoting the progress of management to advance Chinas economic development. 15 years, many key players with the "world managers" influence with Chinese management: development of the countrys rapid economic development strategy of the leader, Deng Xiaoping; survive global competition, and create a new management model for commercial idol Bill Gates Jack Welch; led the great achievements of Chinese enterprises business leaders Li Ka-shing, Zhang, Liu; stimulate excellent practice management guru Philip Kotler ... ...
In certain frequency range, the ratio of crosstalk and attenuation relationship is reflected in the performance of cable to another important parameter. ACR is sometimes said to noise ratio, which consists of the worst value of attenuation and NEXT margin calculations. ACR is large, indicating a stronger anti-interference ability. General system requires at least greater than 10 dB. The quality of the communication channel is described by its cable properties. SNR is the signal interference, taking into account the circumstances, a measure of signal strength data. If the SNR is too low, will cause the data signal is received, the receiver can not distinguish between data signals and noise signals, and ultimately lead to data errors. Therefore, in order to limit data errors within a certain range, you must define a minimum can be received SNR. In testing these indicators in several different ways, and its target requirements are slightly different. These performance indicators are in accordance with the requirements of the physical characteristics of the cable, the people in the real network applications, the transmission bandwidth is more like to know what exactly should meet the requirements. In the cable analysis, the physical bandwidth and data transfer bandwidth are two completely different concepts. Shannon can be seen from the theorem of bandwidth and data transfer bandwidth of physical relationship between:
