Answer
In an op-amp bistable multivibrator circuit, the op amp operates as a summing amplifier, which allows it to switch states based on input signals.
Step 3
A/an … changes its output state when a trigger pulse is received. It remains in that state for a time determined by the RC time constant. Therefore, it returns to its original state.
