A will come out of the column first then component B will come out.
Smaller D means the corresponding smaller component will spend more time in the spaces present in the column. So it will take a longer time to elute out. While a larger component is more likely to avoid such small spaces in a column.
This implies B with DB = 480 will spend comparably more time in column compare to the component A with DA = 500.

When using the K-map to find the equations for DA and DB 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...
