Understanding the Statements
To evaluate the correctness of the statements about flip-flops, let's analyze each one:
1. Race-around condition in JK flip-flop
- A race-around condition occurs in a JK flip-flop when both J and K inputs are high (1, 1). This leads to unpredictable behavior as the output can toggle indefinitely, making this statement correct.
2. Storage capacity of a flip-flop
- A flip-flop is designed to store one bit of information. This is a fundamental characteristic of flip-flops, thus this statement is also correct.
3. Structure of a transparent latch
- A transparent latch is typically based on a D-type flip-flop; however, it is not exclusively defined as such. Transparent latches can be implemented using various types of flip-flops. Therefore, this statement is somewhat misleading but can be considered correct depending on context.
4. Master-slave configuration in flip-flops
- The master-slave configuration in flip-flops is used to ensure stable operation and to prevent race conditions. However, it does not store two bits of information; it still stores one bit but allows for edge-triggered behavior. This statement is incorrect.
Conclusion
Based on the analysis:
- Statements 1 and 2 are correct.
- Statement 3 is correct in the context of D-type flip-flops.
- Statement 4 is incorrect.
Thus, the correct answer is option 'A': Only 1, 2, and 3 are correct.
