This way, the equalizer coefficient Eq ctr changes in response to accumulated changes in {HEAD ~ the NRZ data} timing {TAIL ~ information} , and abrupt, temporary changes in the NRZ data timing information would not necessarily result in a change of the equalizer coefficient Eq ctr unless it is accumulated enough to exceed or become lower than the predetermined thresholds of the count
