Finding two signals in same sequence, varying strength of one signal.

<p>Here we simulate two signals in the same sequence with the same arrangement as in the previous figure. The first signal’s strength is varied, the second signal’s strength is kept fixed at 0.5. The solid curve in the upper plot is the mean proportion recovered of signal 1 and the lower plot for signal 2 (dots for computed values, line segments to join). The grey dashed and dotted curves are for comparison with a single signal, either in a sequence of total length 500 (dashed) or 400 (dotted), with strength as signal 1 (upper plot) or signal 2 (lower plot). The first signal is still sigmoidal in its proportion found as a function of strength, but sits under the curves for equal strength signal alone (either in 400 or 500 length sequence). When the first signal strength is zero, the proportion of the second signal found matches that of a single signal of strength 0.5 in a sequence of length 500. When the first signal is strong the proportion of the second signal found is comparable to a single signal of strength 0.5 in a sequence of length 400. When the first signal is at intermediate strength, its effect of interference on the second signal is most clear.
