Flip Flops

Question 1

What is a Flip Flop?

Answer 1

a basic electronic circuit utilised for storing binary data.

capable of holding on to (‘remembering’) a single bit (either 0 or 1) of binary data.

are constitutive elements of various storage devices, registers, and memory units.

used for transfers of digital data and system synchronisation.

Question 2

D flip flop

Answer 2

Has a single data input (D).

Transfers the D input to output (Q) on clock edge, ensuring a stable output.

Operates on the rising or falling edge of the clock.

Used for data storage, registers, and timing circuits.

Question 3

JK flip flop

Answer 3

Has 2 inputs, J and K, where J sets the flip-flop and K resets it.

Sets, resets, or toggles the output based on the combination of J and K inputs (no invalid state).

Operates on the clock edge and can toggle on J = K = 1.

Versatile, used in counters, registers, and memory devices.

Question 4

RS flip flop

Answer 4

Has 2 inputs, Set (S) and Reset (R).

Sets the output (Q) to 1 when S = 1 and resets it to 0 when R = 1; invalid when both S and R are 1.

Typically asynchronous but can be clocked.

Simple memory storage and control circuits.
