In order to detect a malfunction in one or both of two parallel channels carrying the same data, in a dynamic manner, the absolute differential value of the outputs of these two channels is determined and such absolute differential value is compared with a threshold value which is a pre-selected percent of the average value of the output from the two channels. If the absolute differential value is less than the threshold value, the average output is coupled to an output line; however, whenever the absolute differential value exceeds the threshold value, all data is rejected and there is no output. |
