Continuous- and Discrete-Time Stimulus Sequences for High Stimulus Rate Paradigm in Evoked Potential Studies
(a) A schematic diagram of a stimulus loop that contains 17 individual stimulus impulses to indicate the repetitive presentations in an experiment. (b) A sweep of stimulus sequence with impulses occurring at to represent a period of stimulus loop in time domain ( ms; Hz). (c) A portion of the Fourier spectrum of the inverse filter . Note that within the frequency band of interest ( Hz), is all below the threshold .
