ABSTRACT:
In a similar-redundant signal system employing two or more channels, the signals in the different channels below a predetermined frequency are equalized, the equalization preferably being performed digitally. The equalization reduces the slight differences between signals in the different channels in the absence of channel failure, and thus enables the thresholds for channel failure detection by comparison of the signals in different channels to be reduced.
