Figure 2a
Second, if our understanding of the operation of the
invention is not correct, and there really is simultaneous
transmission of information, then it is not clear how
simultaneous transmission/reception is produced by the
circuits of figures 4 and 5. Figure 4, for example, shows an
MMF having a single input from the left leading to two
modulators 1 and 2; this implies that the same data is
modulated by carrier frequencies F1 and F2. Appellants
description that figure 4 "involves a straightforward control
of the timing of signal inputs to modulators 1 and 2" (Br5) is
not understood since the timing of inputs to modulators 1 and
2 is not controlled. The outputs of the modulators are input
