FIGURE 4-61B

The maximum rate of change allowed by the RMP2 ROC filter block depends upon time.

This time is measured from the beginning of a ramp input to the present time instant. The

maximum rate of change of the output of this filter is time dependent of the form:

Rate = S × T

Equation 4-61.1

where S is the analog value RND (units/Sec.

), and T (Sec.) is the point in time since the

start of the ramp input. The maximum rate of change of the filter output will not exceed

that of the input over a long enough time interval.

As an example, note on Figure 4-61B that the plot starts at time t = 0 Sec. The rate of

change at the input of the filter block is a constant 20 FPM/S. The filter limits the rate of

change block to 5FPM/Sec

thus:

1 2 ... 220 221 222 223 224 225 226 227 228 229 230 ... 465 466
