Abstract

PURPOSE:To enable to show the state of error distribution with the error distribution characteristics indicated with the length of error production and the number of times of error generation, by detecting the length of error production and storing the number of times of production to the memory location taking the length as the address. CONSTITUTION:A pseudo random signal read out from a magnetic recording and reproducing system 1 is fed to an error detection circuit 3, it is compared with the reference signal from a reference memory 4, and if an error is produced, an error detection signal is fed to a counter 5. The counter 5 counts the error detection signal continuously produced, and it is reset when the error detection signal is absent, and the count value is fed to a graph memory 6. The content of the address corresponding to the count value is read out from the graph memory 6, the content is increased by one at the one count adder 8 and the counter is reset to the original position. A counter circuit 7 is to obtain the length of accumulated error production.
