What type of multivibrator produces a continuous square wave output?

An astable multivibrator is designed to operate continuously without requiring any external triggering, resulting in a continuous square wave output. This multivibrator oscillates between two unstable states, creating a square wave signal as it transitions back and forth between these states.

The two key components that facilitate this functioning are typically resistors and capacitors, which determine the frequency of the oscillation. The output waveform alternates between high and low states at a specific frequency, producing the square wave.

Monostable multivibrators, on the other hand, produce a single output pulse in response to an input triggering event, hence not generating a continuous waveform. Bistable multivibrators are stable in both of their states and require an external trigger to switch from one state to another, meaning they also do not produce a continuous output. While a capacitor-resistor circuit can be a part of an astable multivibrator setup, it does not specifically define the multivibrator type nor guarantee a continuous square wave output by itself.
