Abstract
A system of the transversal type automatic equalizer with a tap coefficient protection in which an inter-symbol interference is prevented. The system includes a summing unit for summing all of the tap powers detected by tap power detecting unit, and a determination unit for comparing the sum produced by the summing unit with a predetermined threshold value, and for producing the output determination of normal when the sum is not more than the threshold value and producing the output determination of abnormal tap coefficient growth when the sum is more than the threshold value.
