Figure 7. Plot of total Channel energy and the transfer function T(t) from Channel II to Channel I, for the "Pre-Stemmons" segment. The solid curve is for the Channel-II energy and the broken curve is for the Channel-I energy. T(t) (represented by Δ) is plotted only for frames containing a Channel-II brieftone. Timings of the "Shots" and the Channel-II heterodynes are also indicated. Note the large reduction in T(t) after the Channel-I heterodyne begins.
