Abstract

PURPOSE:To estimate the error factor of the data, by converting the received data into a digital data on the 2-dimensional coordinates and counting the number of digital data approximate to the line of decision set on the 2-dimensional coordinates. CONSTITUTION:A received data Din is converted into a digital data D d of an eye pattern via an MODEM15. The data Dd is apparated to a data error deciding circuit 72 via a level converter 71. The digital data Dr1 and Dr2 corresponding to the line of decision set in the region where the data Dd must not exist are applied to the circuit 72 via a gate 74. The circuit 72 obtains the coincidence between both inputs, and the coincidence signal is applied to a counter circuit 73. Then the error factor is estimated by the count value of the circuit 73.
