Two conditions of temporary stability and no permanent condition of stability refer to which type of multivibrator?

• A. Astable Multivibrator
• B. Monostable Multivibrator
• C. Bistable Multivibrator
• D. Schmitt Trigger

Answer: (A)

This describes an astable multivibrator, a circuit that has no stable output state and continuously switches between its two outputs. In this type, feedback with timing components (like capacitors and resistors) drives the circuit to a state briefly, then causes it to flip to the other state as the timing elements charge and discharge. Because there’s no state that remains steady, the output keeps oscillating on its own. This differs from a monostable, which has one stable state and produces a temporary output after a trigger before returning to that stable state. It also differs from a bistable, which has two stable states and stays in one until deliberately switched. A Schmitt Trigger is a comparator with hysteresis used for clean switching and isn’t by itself a self-oscillating multivibrator.
