Another term for an alternating relay is a ___ relay.

An alternating relay is commonly referred to using alternate terms, one being "impulse relay" and the other being "flip-flop relay." Both terms describe a type of relay that alternates its state in response to input signals.

An impulse relay operates by changing its state with an input signal, holding that state until another input signal is received, thus creating an alternating effect. Similarly, a flip-flop relay also toggles between states and can be set to alternate its output based on trigger conditions.

This function of alternating from one state to another is integral to the concept of such relays, making both terms valid. Therefore, saying "either a or b" accurately reflects the interchangeable nature of the terms used to describe alternating relays.
