Abstract :
This work proposes a functional approach for fault modeling in 2 nd order filters and presents a new use for the transient analysis method for fault detection. The approach considers the filter as a 2nd order dynamic system and the use of the peak time and the system overshoot as observed parameters. The input stimuli are compact test vectors which consist of a step, ramp or parabola. The obtained results show that 100% of soft faults can be detected
