AUTOMATIC DATA SEPARATING CIRCUIT

摘要

PURPOSE:To prevent an error which is caused by the misreading, by comparing the data error frequencies of two or three data separating circuits having different data separating levels and controlling the data separating level at the optimum point at which the data error frequency is minimized. CONSTITUTION:The data separating circuits Amand Am+1 consisting of a comparator 3 and a data strobe circuit 4 have two systems respectively. A data error detecting circuit 8 and a counter 9 which counts the error occurring frequencies are connected to each data separating circuit. The data separating levels are set at different points for the circuits Am and Am+1. The data error frequencies of the circuits Am and Am+1 are compared with each other through a comparator 10. Then the data separating level is controlled at the optimum point where the data error frequency is minimized.
