A glitch filter processes overlapping time sequences of an odd number, N, of potentially corrupted sampled data values to determine the central value for a sorted ordering of each set of N values present for each time interval, t i This central value is taken as the output value for the current set of N input values (i. e. for time interval, t i). In the following time interval, t i + 1, the oldest of the previous N samples is discarded and a new sample is added to the set. This process repeats for each time interval. In an illustrative hardware embodiment, a circuit, such as a FPLA, uses the abovedescribed technique to eliminate glitches occurring in signals otherwise being processed. In an illustrative software embodiment, a processor executes a software routine or computer program to similarly evaluate and eliminate glitches imposed on desired signals.
