Fig. 1. Separation of a mixed electric organ discharge (EOD) recording into pulses
from males and females using cross correlation analysis. (A) The original
mixed recording voltage (V) versus time (s). Exemplar male
and female EOD templates are expanded on the right. (B)
(V*m)2 as function of time. Where
V is the original voltage trace, m is the male exemplar EOD
and the operator * is the cross correlation. All squared
coefficients are positive. (C) The same for the female template. To the right
in A and B (V*m)2 is compared with
(V*f)2 for a male EOD showing how the
cross correlation is higher for the male (green) than female (red) model; C
shows the same for a female EOD. EODs are subsequently identified for every
pulse in the 2-s recording. (D,E) Inter-pulse intervals versus time
for male and female, respectively.
