DATA COMPRESSION OF WAVEFORMS ASSOCIATED WITH A CHEMICAL EVENT OCCURING ON A SENSOR ARRAY

摘要

A method, a computer program and an apparatus for measuring a waveform associated with a chemical event occurring on an ISFET sensor array. The waveform includes at least one region associated with expected measured values and at least one region associated with unpredictable measured values. First frame averaging is applied to at least one region associated with the expected measured values. Second frame averaging is applied to at least one region associated with the unpredictable measured values. The second number of frames used for averaging is less than the first number of frames. By the variable frame averaging the amount of stored data can be reduced.
