CONVENTIONS FOR THE APPLICATION
OF DEPENDENCY NOTATION IN GENERAL. The
rules for applying dependency relationships in
general
follow the same pattern as was illustrated for
G dependency.
8-74. Application of dependency notation is accom-
plished by:
a. Labeling the input (or output) affecting other
inputs or outputs with the letter symbol indicating the
relationship involved (e.g., G for AND) followed by an
identifying number, appropriately chosen, and;
b. Labeling each input or output affected by that
affecting
input (or output) with the same number.
8-75. If it is the complement of the internal logic state
of the affecting input or output that does the affecting,
then a bar
is placed over the identifying numbers at the
affected inputs or outputs. See Figure 8-5.
8-76. If two affecting inputs or outputs have the
same letter and same identifying number, they stand
in an OR relationship to each other. See Figure 8-8.

b G1
c 1

8-77. If the affected input or output requires a label
to denote its function (e.g., "D"), this label will be
prefixed by the identifying number of the affecting
input. See Figure 8-14.
8-78. If an input or output is affected by more than
one affecting input, the identifying numbers of each of
the affecting inputs will appear in the label of the
affected
one, separated by commas. The normal read-
ing
order of these numbers is the same as the sequence
of the affecting relationships. See Figure 8-14. ·
8-79. If the labels denoting the functions of affected
inputs or outputs must be numbers (e.g., outputs of a
coder),
the identifying numbers to be associated with
both affecting inputs and affected inputs or outputs
will be replaced by another character selected to
avoid ambiguity, e.g., Greek letters. See Figure 8-9.

8-80. V (OR) DEPENDENCY. The symbol denoting
OR dependency is the letter V. See Figure 8-10.

8-81. When a Vm input or output stands at its
internal1 state, all inputs and outputs affected by Vm
stand at
their internal1 states. When the Vm input or
output stands at its internal 0 state, all inputs and
outputs affected by Vm stand at their normally
defined internal logic states.
8-82. N (NEGATE,
X-OR) DEPENDENCY. The
symbol denoting negate dependency is the letter N.
See Figure 8-11. Each input or output affected by an
Nm input or output stands in an exclusive-OR
relationship
with the Nm input or output.
If a = 0, then c =b
If a = 1, then c= b
