What is the race around condition in J-K flip-flop?
For J-K flip-flop, if J=K=1, and if clk=1 for a long period of time, then output Q will toggle as long as CLK remains high which makes the output unstable or uncertain. This is called a race around condition in J-K flip-flop.
What is Race condition in flip flop?
Race condition occur in RS flip-flop. When the S and R inputs of an SR flip flop is at logical 1 and then the input is changed to any other condition, then the output becomes unpredictable and this is called the race around condition.
What is the race around condition of a J-K flip-flop How can it be avoided?
This problem is called race around condition in J-K flip-flop. This problem (Race Around Condition) can be avoided by ensuring that the clock input is at logic “1” only for a very short time. This introduced the concept of Master Slave JK flip flop.
What is race around condition in flip flop Mcq?
This set of Digital Electronics/Circuits Multiple Choice Questions & Answers (MCQs) focuses on “Master-Slave Flip-Flops”. Explanation: 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.
Is race condition and race around condition same?
The race around condition happens when current output triggers a change in future output (as in the case of JK flip flop). Within the same clock pulse, the output keeps changing. (resulting in a race between 0 & 1)
What race is FF around condition?
What is race around condition and how it is eliminated?
Race around condition can be eliminated using the master-slave flip-flop. Master-Slave flip-flop is the cascaded combination of two flip-flops among which the first is designated as master flip-flop while the next is called slave flip-flop.
What is a race condition Mcq?
A Race condition refers to. A situation where several processes access and manipulate the same data concurrently. A situation where Single process access and manipulate the same data concurrently . A situation where No process access and manipulate the same data concurrently.
Which scenario race condition occurs Mcq?
“A race condition occurs when multiple processes or threads read and write”, principles of concurrency Multiple Choice Questions (MCQs) with choices information, input, data items, and programs for top computer science schools in the world.
What is meant by race condition?
A race condition occurs when two threads access a shared variable at the same time. Then the first thread and second thread perform their operations on the value, and they race to see which thread can write the value last to the shared variable.
What is the race around condition in JK flip flop?
This problem is called race around condition in J-K flip-flop. This problem (Race Around Condition) can be avoided by ensuring that the clock input is at logic “1” only for a very short time. This introduced the concept of Master Slave JK flip flop.
When is the output of an SR flipflop unstable?
When the S and R inputs of an SR flipflop is at logical 1, then the output becomes unstable and it is known as race condition. When the S and R inputs of an SR flipflop is at logical 1 and then the input is changed to any other condition, then the output becomes unpredictable and this is called the race condition. Which one is right?
What makes a JK flip flop a synchronous device?
Toggling takes place during the whole process since the output is changing once in a cycle. This makes the Master-Slave J-K flip flop a Synchronous device as it only passes data with the timing of the clock signal.
How is a Master flip flop connected to a slave flip flop?
The Master-Slave Flip-Flop is basically a combination of two JK flip-flops connected together in a series configuration. Out of these, one acts as the “master” and the other as a “slave”. The output from the master flip flop is connected to the two inputs of the slave flip flop whose output is fed back to inputs of the master flip flop.
