Question

The months of the years are coded in four variables, STUV, such that January is 1011, February is 1010.....and December is 0000. The remaining four combinations are never used. (Remember 30 days has September, April June and November, all the rest has 31, except February) Create the truth table for a function, "M", that is 1 if the month has 31 days and 0 if it does not 11) 12) Implement the truth table for problem,11, using two 3 out of 8 decoders shown (the function table is provided). Clearly show the how the inputs, STUV are connected to the decoders inputs and enables ("G" inputs) and the decoder outputs are connected to implement the function"M" SELECT GL G1 G2 C B A İYO Y1 Y2 Y3 Y4 Y5 Y6 Y7 X X1 0 10 0 01 0 100 1 1 1 0 0 1 0 01 1 0 1 0 0 1 0 X X X Output corresponding to stored address 0; all others 1 Y1 Y3 Y4 G1 G2B Y6 74LS138N
