| Description |
Computes the Woody average by first aligning individual signals (corrupted by jitter) with the standard average. Uses xcorr to compute the lag and then re-averages the signals to get an improved estimate.
Example included in help.
Technique deteriorates at low SNRs. |

Added a variation of the Woody that is suppose to yield better results at lower SNR.For details see:
