System and method for adaptive stimulus-response signal filtering

A system for buffering a noisy signal comprising multiple instances of a signal of interest added to noise, wherein each instance of the signal of interest is causally related to a stimulus, the system comprising:

• an input module for receiving the noisy signal while a plurality of stimuli occur, each stimulus corresponding to a distinct instance of the signal of interest;
• a plurality of memory buffers;
• a processor configured to:
• receive the noisy signal from the input module;
• assign a plurality of segments of the noisy signal, each segment corresponding to a stimulus, to the plurality of memory buffers in a biased manner so that the reliability of a comparative statistic is increased;
• and
• an output module configured to output the contents of at least one of the plurality of memory buffers or a value of the comparative statistic for further processing.

• a plurality of memory buffers;
• a processor configured to:
• receive the noisy signal from the input module;
• recursively, for a predetermined number of times:
• randomly order a plurality of segments of the noisy signal and assign the plurality of segments of the noisy signal to the plurality of memory buffers in a random manner;
• calculate a comparative statistic for each random ordering;
• select a random ordering having a final comparative statistic that is representative of a distribution of the comparative statistics
• an output module configured to output the selected random ordering for further processing.
