The output changes state only when any of the input is triggeredī. How many types of triggering take place in a flip flops?Ĭlarification: There are three types of triggering in a flip-flop, viz., level triggering, edge triggering and pulse triggering.Ĭlarification: Flip-flops are synchronous bistable devices known as bistable multivibrators as they have 2 stable states.ġ3. Also, the JK flip-flop resolves the Forbidden State.ġ1. Which of the following is the Universal Flip-flop?Ĭlarification: There are lots of flip-flops can be prepared by using J-K flip-flop.
D edge triggered flip flop free#
Which of the following flip-flops is free from the race around the problem?Ĭlarification: 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.ġ0. S-R type flip-flop can be converted into D type flip-flop if S is connected to R through _Ĭlarification: S-R type flip-flop can be converted into D type flip-flop if S is connected to R through an Inverter gate.ĩ. SR flip-flop is not suitable as it produces the “Invalid State”.Ĩ. If one wants to design a binary counter, the preferred type of flip-flop is _Ĭlarification: 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. In a positive edge triggered JK flip flop, a low J and low K produces?Ĭlarification: In JK Flip Flop if J = K = 0 then it holds its current state. Master slave flip flop is also referred to as?Ĭlarification: 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.Ħ. The situation is referred to as?Ĭlarification: 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.ĥ. At the end of the clock pulse the value of output Q is uncertain. at a particular time or during a clock pulse, the output will oscillate back and forth between 0 and 1. Two of them are connected with each other.Ĥ. D flip-flop is a circuit having _Ĭlarification: D flip-flop is a circuit having 4 NAND gates. Input clock of RS flip-flop is given to _Ĭlarification: Pulser behaves like an arithmetic operator, to perform the operation or determination of corresponding states.ģ. The asynchronous input can be used to set the flip-flop to the _Ĭlarification: 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.Ģ.
