Which of the following is NOT a form of signal coupling between two (2) circuits?
Which of the following is NOT a form of signal coupling between two (2) circuits?
In signal coupling between circuits, common methods include conductive, inductive, capacitive, and electromagnetic coupling. Reactive coupling is not a recognized form of signal coupling. Reactance refers to the opposition to the flow of alternating current within a circuit, not a method of coupling signals between separate circuits.
Reactance is opposition to the flow of ac current (page. 257)
