Astable Multivibrator shifts between two states thereby generating a square wave. In Bistable Multivibrator, a trigger pulse is needed for change from one stable state to another stable state (from 0 to 1 and 1 to 0) hence can be used to state binary data.

Astable Multivibrator:
- An astable multivibrator is a type of electronic circuit that generates a continuous square wave output signal.
- It consists of two amplifying devices such as transistors or operational amplifiers connected in a feedback loop.
- The circuit operates in two stable states and continuously switches between them, creating the square wave output.
- It does not require any external trigger or input signal to operate.
- The time period of the generated square wave can be controlled by adjusting the components in the circuit.
- The output waveform of an astable multivibrator does not have a stable state and continuously oscillates between high and low states, hence the name "astable".
Uses of Astable Multivibrator:
- Generating Square Wave: The main application of an astable multivibrator is to generate square wave signals.
- Timing Circuits: It is commonly used in timing circuits, such as in clocks, timers, and frequency generators.
Bistable Multivibrator:
- A bistable multivibrator, also known as a flip-flop, is a circuit that has two stable states and stays in either state until a trigger is applied to change its state.
- It consists of two amplifying devices with feedback, similar to an astable multivibrator, but with an additional input for triggering.
- The circuit maintains its current state (high or low) until a trigger pulse is applied, which causes it to switch to the opposite state.
- Bistable multivibrators can store binary information, as they have two stable states that represent logic 0 and logic 1.
Uses of Bistable Multivibrator:
- Memory Elements: Bistable multivibrators are widely used as memory elements in digital circuits.
- Storage of Binary Information: They can store binary information and are commonly used in registers, counters, and flip-flops.
Explanation of the Correct Answer:
- Statement 1 is correct because an astable multivibrator can be used for generating a square wave.
- Statement 2 is correct because a bistable multivibrator can be used for storing binary information.
- Therefore, both statements 1 and 2 are correct, making option C the correct answer.
