Explanation:
An S-R (Set-Reset) flip-flop is a basic building block of digital circuits. It has two inputs, namely S (Set) and R (Reset), and two outputs, namely Q (Output) and Q' (Complement of Output). The flip-flop can be positive edge-triggered, meaning the outputs change based on the condition of the inputs at the rising edge of the clock pulse.
Inputs:
- S (Set) input: When this input is HIGH, it sets the Q output to HIGH (Q=1).
- R (Reset) input: When this input is HIGH, it resets the Q output to LOW (Q=0).
Outputs:
- Q (Output): Represents the current state of the flip-flop. It can be either HIGH (Q=1) or LOW (Q=0).
- Q' (Complement of Output): Represents the opposite state of the Q output. If Q is HIGH, Q' is LOW, and vice versa.
Working of Positive Edge-Triggered S-R Flip-Flop:
The positive edge-triggered S-R flip-flop changes its outputs only when there is a transition from LOW to HIGH on the clock pulse. This means that the clock pulse must be LOW initially and then transition to HIGH for the input condition to be reflected in the outputs.
When the clock pulse is LOW, the inputs S and R are effectively disabled, and their values do not affect the outputs. The outputs remain in their previous state.
When the clock pulse transitions from LOW to HIGH, the inputs S and R are enabled, and their values at this moment determine the new state of the outputs. The flip-flop will respond to the inputs and update the outputs accordingly.
Thus, the outputs of a positive edge-triggered S-R flip-flop reflect the input condition when the clock pulse transitions from LOW to HIGH. This is because the flip-flop captures the inputs at the rising edge of the clock pulse and updates its outputs based on those inputs.
In summary:
The correct answer is option C) The clock pulse transitions from LOW to HIGH. This is when the inputs are captured and the outputs reflect the input condition in a positive edge-triggered S-R flip-flop.

Edge triggered device will follow the input condition when there is a transition. It is said to be positive edge triggered when transition occurs from LOW to HIGH. While it is said to be a negative edge triggered when a transition occurs from HIGH to LOW.
