Abstract
Methods and apparatuses for comparing redundant signals in functional safe systems are provided, including methods for mitigating differing signal path delays and for signal weighting of the redundant signals are proposed. An Apparatus includes a first signal path for a first measurement signal of a physical quantity, the first signal path having a first signal propagation delay; a second signal path for a second measurement signal of the physical quantity, the second signal path having a second signal propagation delay different from the first signal propagation delay; a delay compensation circuit configured to compensate for a difference between the first and second signal propagation delays to generate delay-compensated first and second measurement signals; and comparison circuitry configured to compare the delay-compensated first and second measurement signals.
