Apparatus for providing parallel filtering

A system comprising:

• a first circuit comprising:
• a first filter filtering a first input signal indicative of at least a sensed voltage condition, the first filter generating a first filtered output signal in response to filtering the first input signal at a first frequency, and
• a first comparator comparing the first filtered output signal to a first threshold value and providing a first output signal indicative of a failure condition to one or more first processors to report the failure condition based on the comparison of the first filtered output signal to the first threshold value;
• and
• a second circuit comprising:
• a second filter filtering the first input signal indicative of the at least the sensed voltage condition within the system, the second filter generating a second filtered output signal in response to filtering the first input signal at a second frequency that is greater than the first frequency enabling the second filter to filter the first input signal in less time than the first filter filtering the first input signal, and
• a second comparator comparing the second filtered output signal to a second threshold value and providing a second output signal indicative of the failure condition to one or more second processors,
• wherein the first frequency of the first filter is based at least on a first time constant and the second frequency of the second filter is based at least on a second time constant, and
• wherein the second time constant is less than the first time constant causing the second filter to filter the first input signal in less time than the first filter filtering the first input signal.

A system comprising:

• a first filter filtering a first input signal indicative of at least a sensed voltage condition in the system, the first filter generating a first filtered output signal in response to filtering the first input signal at a first frequency, and
• a first comparator comparing the first filtered output signal to a first threshold value and providing a first output signal indicative of a failure condition to one or more first processors to report the failure condition based on the comparison of the first filtered output signal to the first threshold value;
• and
• a second filter filtering the first input signal indicative of the at least the sensed voltage condition within the system, the second filter generating a second filtered output signal in response to filtering the first input signal at a second frequency that is different than the first frequency enabling the second filter to filter the first input signal in less time than the first filter filtering the first input signal, and
• a second comparator comparing the second filtered output signal to a second threshold value and providing a second output signal indicative of the failure condition to one or more second processors disabling the system prior to the one or more first processors reporting the failure condition based on the comparison of the second filtered output signal to the second threshold value.
