A theoretical relationship was derived among the number of trials averaged (N), initial signal-to-noise ratio (SNR) and correlation coefficient (r). The validity of this relationship was tested with simulations using one cycle sinusoidal signal and two kinds of noises, namely, white gaussian noise and rat EEG. By selecting 0.95 as an acceptable r value, the adequate average number could be determined under different SNR conditions.
