A New Approach to the Evaluation of the Reliability of Digital Systems

Signal reliability, as a measure of digital systems´ reliability, has not been used until recently due to lack of efficient evaluation methods. A new approach to the evaluation of signal reliability is presented in this work. A reliability transfer function of digital systems is defined and a method for its evaluation is presented. This approach provides a new insight into the problem of digital system reliability. Furthermore, it simplifies signal reliability calculations and can easily be mechanized.
