3.Assume the
÷
N counter and the
÷
A counter (with all the
higher order bits above “a” ignored) combined into a
single binary counter of n + a bits in length (n = number
of divider stages in the
÷
N counter). The MSB of this “hy-
pothetical” counter is to correspond to the MSB of
÷
N and
the LSB is to correspond to the LSB of
÷
A. The system
divide value, NT, now results when the value of NT in
binary is used to program the “new” n + a bit counter.
By using the two devices, several dual–modulus values
are achievable (shown in Figure 13).
