Abstract

Glitch filters, methods, and computer program products that utilize the generally monotonically increasing characteristics of the expected levels of code points to detect and remove noise spikes by replacing values in the code point sequence with new values based on the code points around a suspect value are provided. Measured values associated with two code points in the sequence of code points which are immediately higher in the sequence of code points than a code point of interest are evaluated so as to select a larger value of the two code points in the sequence as a first reference value. The first reference value is compared with a measured value associated with a code point in the sequence of code points immediately lower than the code point of interest to determine if the first reference value is smaller than the measured value associated with the code point in the sequence of code points immediately lower than the code point of interest. The smaller of the first reference value and the measured value associated with a code point in the sequence of code points immediately lower than the code point of interest is then selected so as to provide a first replacement value. The measured value associated with the code point of interest is then replaced with the first replacement value if the first reference value is smaller than the measured value associated with the code point of interest.
