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 (probability = .10) and 1000 Hz (probability = .90) tones was presented to one male subject. The EEG from Cz and Pz was recorded simultaneously at time constants of 0.1, 0.3, 1.0, and 10.0 sec. The ERP waveform was markedly affected by the time constant: the shorter the time constant, the smaller the amplitude of both the P300 and Slow Wave components.
