Input clock of RS flip-flop is given to ____________

The correct answer is option 'B', which is "Pulser".

Explanation:
A RS flip-flop, also known as a bistable multivibrator, is a simple digital circuit with two stable states. It has two inputs, labeled as "R" (Reset) and "S" (Set), and two outputs, labeled as "Q" and "Q̅" (the complement of Q).

The operation of an RS flip-flop is controlled by an external clock signal, which is usually referred to as the "input clock". The input clock determines when the inputs are read and the outputs are updated. It synchronizes the operation of the flip-flop with the rest of the digital circuit.

The input clock is typically a pulsed signal that transitions between two states, such as 0V (low or logic 0) and 5V (high or logic 1), at regular intervals. This pulsed signal provides the timing required for the flip-flop to change its state based on the inputs.

The input clock signal is connected to the clock input of the RS flip-flop. When a rising or falling edge of the clock signal occurs, the flip-flop samples the inputs and updates the outputs accordingly. The specific behavior of the RS flip-flop depends on its internal logic circuitry.

It is important to note that the input clock is not directly connected to the inputs or outputs of the flip-flop. Its sole purpose is to control the timing of the flip-flop's operation. The inputs, such as the "R" and "S" inputs, determine the desired state of the flip-flop, while the outputs, such as "Q" and "Q̅", reflect the current state of the flip-flop.

In summary, the input clock of an RS flip-flop is connected to a pulser, which is a pulsed signal that controls the timing of the flip-flop's operation.
