Q

What is an astable multivibrator?

🔍 Key Concepts

• Meaning of astable, monostable, and bistable multivibrators in electronics • How many stable states an astable circuit has • The typical use of an astable multivibrator as an oscillator or clock signal source

💭 Think About

• Ask yourself: in an astable circuit, if you power it up and leave it alone, does it ever settle in one state, or does it keep changing? • Compare each option with the exact definition of stable state (a state the circuit can remain in indefinitely without external triggering). • Which choice describes a circuit that produces a continuous stream of pulses by itself, without needing repeated external triggers?

✅ Before You Answer

• Identify how many stable states an astable multivibrator has (zero, one, or two). • Eliminate any option that incorrectly describes the number of stable states. • Verify which type of multivibrator (mono-, bi-, or a-stable) corresponds to continuous free-running oscillation.
