Oscillatory failure monitor |
摘要 |
An oscillatory-failure monitor (101) compares a parameter of a plurality of signals (A, B) within a tolerance (TOL) to determine agreement or disparity among the signals. Each discrete miscompare occurrence (i.e., singular disparity following full agreement) is counted by incrementing (27; 54) a counter (OSCCT; CNTR). The counter is decremented (32; 62) whenever the signals compare for a predetermined time interval (29; 47). An oscillatory-failure is declared when the counter increments to a threshold (28, 21; 57, 58, 60). Both digital (FIG. 1) and dedicated hardware (FIG. 4) embodiments are disclosed.
