Which term refers to the controller output associated with one or more phases?

• A. Overlapped signals
• B. Phase output
• C. Controller signal
• D. Overlap

Answer: (D)

Think about what happens when a controller’s output can affect more than one phase at the same time. In multi-phase systems, there are moments when the control signal isn’t tied to a single phase but overlaps across phases. That shared, simultaneous activity is described by the term overlap. It encapsulates the idea that the controller output is linked to one or more phases at once, especially during transitions. The other terms don’t fit as well: a phase-specific output implies just one phase; a generic controller signal is too broad; and overlapped signals isn’t the standard way to name this behavior.
