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
Replace the T input by sbar rbar q bar + sbar r q
g => (g or h) => (s and t) => t => (t or u) => (c and d) => c.We are given premises:# (g or h) -> (s and t) # (t or u) -> (c and d) We would like to derive g -> c.If we assume g (the antecedent in the conclusion) we have the following derivation: # g (assumption) # g or h(weakening) # s and t (premise 1 (modus ponens)) # t(weakening) # t or u (weakening) # c and d (premise 2 (modus ponens)) # c (weakening)So, assuming g we can derive c, i.e. g -> c

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...
it will be the X-OR gate of D and the output Q
Replace the T input by sbar rbar q bar + sbar r q
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.
tie inputs together
QN+1=T exor QN
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.
This flip-flop toggles (Q changes state) on the negative going edge of the clock pulse. T acts as an ENABLE / INHIBIT control. Q will only toggle on the negative edge of the clock pulse, when T is high. Below is shown a D type flip-flop connected as a toggle type. On each clock pulse positive going edge, Q will go to the state bar Q was before the clock pulse arrived. Remember that bar Q is the opposite level to Q. Therefore Q will toggle.
