Resumen

PERETTI, G.; ROMERO, E.  y  MARQUES, C.. Test of nuclear-pulse shapers using oscillation-based test. Lat. Am. appl. res. [online]. 2007, vol.37, n.3, pp. 163-170. ISSN 0327-0793.

This paper addresses the problem of testing continuous-time nuclear-pulse shapers using Oscillation-Based Test (OBT). The proposal is to convert the whole systems into non-linear oscillators, avoiding the partition in low-order sections. The design of the oscillators is very simple because the non-linear elements are mathematically modeled using the describing function approach, and the study of the oscillators is made using techniques of linear systems. The test strategy presents high fault coverage and requires only one test session. The last characteristic allows reducing the time required for executing the test and the complexity of the test controller. The OBT schemes are validated using deviation and catastrophic fault models.
