Abstract

PURPOSE:To judge a data multiplexed for optional number of times by integrat ing the result of software decision and comparing it with a threshold value corresponding to number of times of multiplex. CONSTITUTION:A threshold value in response to each number of times of multiplexing is set to a comparator 4 and the result of addition being an output of an adder 3 at the present point of time is decided as to whether it is higher or lower than each threshold value. Then a selector 5 of the next stage selects a line corresponding to number of times of multiplex transmission to decide the data value. The data level whether it is high or low is outputted by the software decision when the number of times of multiplexing is known as to the data. When the data level is discriminated to be low, the content of a count er A is detected as it is as the number of mis-recognitions of data and when the data is discriminated to be high, the rest being the subtraction of the content of the counter A from the data multiplex number is detected similarly as the misrecognition number of data.
