no indeterminate state
The first flip-flop was invented in 1919 and is called the Eccles-Jordan Trigger Circuit, for its two coinventors. It was a Toggle flip-flop, with only a Clock input. It had false triggering and stability problems, but found much use in cosmic ray and radiation meter scaling counters. Much literature even well into the 1960s still referred to flip-flops as Triggers.
The word flip-flop as applied to these circuits comes from the sound produced when one output was used to drive a speaker.
JK allows you to toggle without knowing the previous state.
we cannot have input 1,1 this is disadvantage,but the circuit is simple the advantage
The question is asking the difference between two identical things - SR and SR flip flops. Please restate the question.
jk does not have invalid condition

Yes. You need two gated input SR flipflops, and an inverter. Connect the Q output of the first flipflop to the S of the second. Connect the notQ output of the first flipflop to the R of the second. Connect the clock to the gate input of the second flipflop, and to the input of the inverter. Connect the output of the inverter to the gate of the first flipflop.
The "Race Around Condition" occurs when J+K=1 i.e. When the FF is in the toggle mode.the race around condition in JK latch can be avoided by:a) Using the edge triggered JK flip flop.b) Using the master slave JK flip flop.
When the inputs J and k of the JK flip-flop are set to 1, the output toggles.

tie both J & K high.
A plain JK flipflop is unreliable as it is enabled by the level of the clock, not the edge. In a master-slave flipflop, the master section captures the new state based on the inputs while the clock level is high, then the slave section captures the new state from the master while the clock level is low. This has the effect of making the flipflop act as if it was falling edge clocked but retains the simplicity of design of flipflops that are level enabled.
in SR flip flop when we have S=1 R=1 we get intermediate state In JK flip flop we eliminate the intermediate state by complement Q- ( J=1,K=1 Q+ = (Q-)') so we can say that JK flip flop is refinement of SR flip flop Amjad Al.Haqpani
by combining j and k inputs we will get jk flipflop
JK flip flop are synchronous ONLY when the rise or the fall edge of the clock will transfer the data to the outputs

Yes. You need two gated input SR flipflops, and an inverter. Connect the Q output of the first flipflop to the S of the second. Connect the notQ output of the first flipflop to the R of the second. Connect the clock to the gate input of the second flipflop, and to the input of the inverter. Connect the output of the inverter to the gate of the first flipflop.
Actually, the choice of the letters "JK" in the JK flip flop do have significance. The JK flip flop was named after Jack Kilby, the Texas Instruments engineer that invented the integrated circuit in 1958. The modified RS circuit that eliminated race conditions was named JK in his honor. Search for "JK" and "Jack Kilby" simultaneously to see multiple sources for this.
J=SET K=RESET NOTE: JK FLIP FLOP IS NOTHING BUT AN ADVANCED VERSION OF THE SET-RESET()SR FLIP FLOP) SO, JK FLIP FLOP ALSO WORKS SOMEWHAT LIKE THE SR FLIP FLOP..... IS ACTUALLY THE LABORATORY TERM OF NUMBER 5 FLIP FLOP 5# J & K.
they had your moms home and something nasty went on!! jk jk jk jk jk jk jk jk lol hehehe i have no idea luv ya byee
JK allows you to toggle without knowing the previous state.
( 12/jk ) x ( 3k/4 ) = 9/j
