Abstract
The checking fidelity of the systems with built-in fault detection circuits is investigated here taking into account the failure rates of functional units, also checking and transmission facilities of right and wrong information on the state of functional units. When fault detection circuits or information transmission facilities fail, then the information given by them may cause false or undetected failures in comparison with the real state of the corresponding functional unit.
