Abstract
PURPOSE: To secure always an optimum slice level automatically even if a data level is fluctuated.
CONSTITUTION: When a slice level rises according to rise of the count value of counter 14 to reach the lower limit of the slice level, framing detection pulse c is generated from framing code detection circuit 24, and Q output e of flip flop 25 rises by sampling pulse d obtained from sampling pulse generation circuit 23. As the result, detection signal f of the slice level lower limit is generated at the output of gate 26, and this signal f is applied to first register 16 to latch the count number of counter 14, and the value of lower-limit slice level V2 is outputted to second D-A converter 18. When counter 14 increases the count number furthermore to reach slice level upper limit V1, the count number at this time is latched in second register 17, and upper-limit slice level V1 is outputted to third D-A converter 19.
