Measuring Latency Variations in Evoked Potential Components Using a Simple Autocorrelation Technique

Figure 5

(a) shows the average of 30 repetitions of the simulated signal (onset latency 90 ms, width 20 ms) with random jitter to a maximum of of similar amplitude, together with the reliability measure (median ) over 50 ms time windows. (b) shows the histogram of the peak time differences which gives maximum correlations for every dissimilar pair of 30 repetitions.
