f)
The input to the XR-2211A may sometimes be too sensitive to noise conditions on the input line.
Figure 4 illustrates
a method of de-sensitizing the XR-2211A from such noisy line conditions by the use of a resistor, Rx, connected
from pin 2 to ground. The value of Rx is chosen by the equation and the desired minimum signal threshold level.
