摘要：

A standard counting task was used to illustrate the effect of the time constant of the recording system on the amplitude and waveform of the P300 component. A random sequence of 1500 Hz (p = .10) and 1000 Hz (p = .90) tones was presented to 1 human male subject. The EEG from CZ and PZ was recorded simultaneously at time constants of 0.1, 0.3, 1.0 and 10.0 s. The ERP [event-related potential] waveforms was markedly affected by the time constant: the shorter the time constant, the smaller the amplitude of both the P300 and slow wave components.
