Question

When using the K-map to find the equations for D_A and D_B for the problem down below_, how can you tell which variable is supposed to be for the row and columns?

How can I tell if the rows for the 2x4 k-maps would be dealing with "A" while the columns would be dealing with "Bx"? Does it even matter how I set up the K-map?

Design a sequential circuit with two D flip-flops A and B, and one input x_in.

When x_in = 0, the state of the circuit remains the same. When x_in =1, the circuit
goes through the state transitions from 00 to 11, to 01, to 10, back to 00, and repeats.

Answer 1

Tnu th table input next State Present state O O K-maps DA 10 11 A/Bx 00 01 A'X+ Ax DA 1 DBX A)B Bx ABX +ABX Bx'+ x(AB+AB')

I think in question ....the order is from 00 to 01 and to 10 ,to 11

But it is different given there.

Coming to k maps , we can take any variable to rows and columns ...we will get the same answer.

Setting up the k map is very easy, just follow the rules of taking correct digits for the variables .

And variables may be in any order ,it will gives the same answer
