Test: Master Slave Flip Flop - Electrical Engineering (EE) MCQ

The asynchronous input can be used to set the flip-flop to the 1 state or clear the flip-flop to the 0 state at any time, regardless of the condition at the other inputs.

D flip-flop is a circuit having 4 NAND gates. Two of them are connected with each other.

The term pulse triggered means the data is entered on the rising edge of the clock pulse, but the output does not reflect the change until the falling edge of the clock pulse.

If one wants to design a binary counter, the preferred type of flip-flop is J-K type because it has capability to recover from toggle condition. SR flip-flop is not suitable as it produces the “Invalid State”.

T flip-flop is free from the race around condition because its output depends only on the input; hence there is no any problem creates as like toggle.

There are three types of triggering in a flip-flop, viz., level triggering, edge triggering and pulse triggering.

The term synchronous means the output changes state only when the clock input is triggered. That is, changes in the output occur in synchronization with the clock.

The circuit that generates a spike in response to a momentary change of input signal is called R-C differentiator circuit.

Pulser behaves like an arithmetic operator, to perform the operation or determination of corresponding states.

A race around condition is a flaw in an electronic system or process whereby the output and result of the process is unexpectedly dependent on the sequence or timing of other events.

In JK Flip Flop if J = K = 0 then it holds its current state. There will be no change.

 S-R type flip-flop can be converted into D type flip-flop if S is connected to R through an Inverter gate.

There are lots of flip-flops can be prepared by using J-K flip-flop. So, the name is a universal flip-flop. Also, the JK flip-flop resolves the Forbidden State.

Flip-flops are synchronous bistable devices known as bistable multivibrators as they have 2 stable states.

The S-R, J-K and D inputs are called synchronous inputs because data on these inputs are transferred to the flip-flop’s output only on the triggering edge or level triggering of the clock pulse. Moreover, flip-flops have a clock input whereas latches don’t. Hence, known as synchronous inputs.
