用于控制等化器的方法和电路与等化系统;METHOD AND CIRCUIT FOR CONTROLLING AN EQUALIZER AND EQUALIZING SYSTEM

摘要

一种用于控制等化器的方法和电路与等化系统。此方法包含在一准位组中提供第一准位为等化器的峰值准位；使用具第一准位的等化器来等化传输讯号，以得到第一讯号；从此准位组中提供第二准位为等化器的峰值准位；使用具第二准位的等化器来等化传输讯号，以得到第二讯号；决定第一讯号的一第一频率；决定第二讯号的第二频率；比较第一频率和该第二频率，以得到比较结果；以及根据比较结果决定等化器的峰值准位，以进行后续对传输讯号的等化。; equalizing a transmission signal by using the equalizer with the first level to obtain a first signal; providing a second level from the set of levels as the peaking level of the equalizer; equalizing the transmission signal by using the equalizer with the second level to obtain a second signal; determining a first frequency of the first signal; determining a second frequency of the second signal; comparing the first frequency and second frequency to obtain a comparing result; and determining the peaking level of the equalizer for following equalization of the transmission signal in accordance with the comparing result.
