Guard Time Adjustment
In many situations not requiring selection of tone duration and interdigital pause, the simple steering circuit shown
in Figure 3 is applicable. Component values are chosen according to the formula:
t

The value of t
DP
is a device parameter (see Figure 7) and t
REC
is the minimum signal duration to be recognized by
the receiver. A value for C of 0.1
μ
F is recommended for most applications, leaving R to be selected by the
designer.
