when i make excitation table of any flip flop i saw sometimes we write Q left side of A, B and sometimes right side of A,B what is the meaning of this plz tell me

like :Q A B A B Q 0 0 0 0 0 0 0 0 1 0 0 1 0 1 0 0 1 0 0 1 1 0 1 1

A majority function is generated in a combinational circuit when the output is equal to 1 if the input variables have more 1’s than 0’s. The output is 0 otherwise. Make a 3-input majority function.

A sequential circuit has two D flip-flops, two inputs x and y, and one output Z is specified by the following next-state and output equations A(t+1) = xy’ + x B B(t+1) = xA +xB’ Z = A (a) Draw the logic diagram of the circuit. (b) List the state table for the sequential circuit. (c) Draw the corresponding state diagram.

Choosing prime implicants in K-maps
I got a K-map with the following boolean function: F(A,B,C,D) = ΠM[3,4,6,9,11,14]+ Σd[0,7,8,10,13,15] In the following K-map following prime-implicants are considered: But I can chose ($\bar{A}$+$\bar{D}$) instead of ($\bar{A}$+$B$) like: So now ... $\bar{C}$+$\bar{D}$)($A$+$C$+$D$) So we get different f in the two cases or am I making a mistake somewhere?
