Replace the T input by sbar rbar q bar + sbar r q
ya its true that we convert the j-k flip flop into s-r flip by using basic gates
step1- write the table of t ff step2-write the excitation table of d ff step3-find out the value of t by k-map then make the d ff according to the value of t
a Juicy Couture Sidekick II that her father bought her.
1 unit = 1 KW X 1 Hour so it means that unit of current can be converted into kWh by multiplying it by the watt and t time taken (in hours).
well in the first season she had a sidekick type phone and in the second season she had a flip phone which I'm not really sure what kind of phone it was and in the third season she had a pink Palm Centro
Tyler Perry did not complete high school, he earned a GED. He never received any college level education.
it will be the X-OR gate of D and the output Q
D Flip flop which have driven the output as the given input there is no change in the I/O. But in the case of T-Flipflop the output is inverted to the given input .i.e complement of the input is output. Thank you i am meganathan...
Toggles flip flop
The JK in JK flip flop stands for Jack Kilby who was the inventor of JK flip flop.His complete name was Jack St. Clair Kilby.
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

tie inputs together
Because 'T' stands for 'Toggle'
toggle condition :- the condition of the flip-flop in which on the application of clock-pulse inverts the present state Q(t+1) = Q'(t) on the application of clock-pulse for JK-flip-flop the toggle condition is J=K=1 for JK flip-flop this is called toggle condition condition
Clock is propagated from one T or JK flip flop to another hence it works. A ripple counter works by the following principle. A clock pulse is applied to the first flip flop and the output of the first flip flop acts as the clock input to the second flip flop and the sequence continues in that order.
toggle: at every clock pulse it switches state.
I am not a Electronic Engineer, so probably any expert out there can correct me if I am thinking wrong.--------- As you can see below there is something common between JK and SR flipflop i.eThe JK flip-flop augments the behavior of the SR flip-flop by interpreting the S = R = 1 condition as a "flip" or toggle command. Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop; and the combination J = K = 1 is a command to toggle the flip-flop, i.e., change its output to the logical complement of its current value. Setting J = K = 0 does NOT result in a D flip-flop, but rather, will hold the current state. To synthesize a D flip-flop, simply set K equal to the complement of J. The JK flip-flop is therefore a universal flip-flop, because it can be configured to work as an SR flip-flop, a D flip-flop or a T flip-flop. NOTE: The flip flop is positive edge triggered (Clock Pulse) as seen in the timing diagram.even in the picture they Put SR/RS embeded, that mens JK can work like SR too. I will use this diagram to draw ripple counter. You may note similarity in input output combination too...RS table* We can summarize the operation of the RS-flipflop by the following truth table.R S Q Q' Comment 0 0 Q Q' Hold state 0 1 1 0 Set 1 0 0 1 Reset 1 1 ? ? AvoidJktableand the corresponding truth table is: J KQnext Comment 0 0 hold state 0 1 reset 1 0 set 1 1 toggleDoes that mean we use below coutner 'using 4 bit ripple counter using JK flip flops' as 4 bit ripple counter for RS flip flop too? at the max output states would differ only when both SR/JK is 1 1 ?Figure 1. A Simple Ripple Counter Consisting of J-K Flip-flopsMethod1: You will find answer here: http://www2.cs.uh.edu/~jhuang/JCH/LD/chap07.htmlHere you see how to create ripple counter using RS flip flop. Method 2: create a Toggle function in RS flip flop, then use it in place of typical jk flip flop ripple couters.
