Optional External Component
Interaction
The optional external components have specific desired func-
tions. Their values are chosen to reduce the bandwidth and
eliminate unwanted high frequency oscillation. They may,
however, cause certain undesirable effects when they inter-
act. Interaction may occur when the components produce
reactions that are nearly equal to one another. One example
