1. Design a circuit with four inputs i, j, x, y, and two outputs b, c. Each of these values is one bit. Use 4-variable Karnaugh maps with dont cares to minimize the functions for outputs b and c.
The circuit will implement all three functions below. Inputs i and j are control inputs that will select one function, then inputs x and y are data inputs that will determine outputs b and c according to the selected function. Assign (and specify in your design) control input values to the functions. For instance, if you assign ij =00 to Function F, then the inputs i =0, j =0, x =0, y =1 will generate the outputs b =1, c =0.
For a function with only one specified output, the values for the other output are dont cares. (For example, for Function G, the c outputs are dont cares.)
Function F
r s b c
0000
0110
1011
11 d d
Function G
r s b
000
011
101
111
Function H
r s c
000
011
100
110
The better your minimization, the easier wiring up a circuit would be.
2. Draw your circuit of logic gates.
3. Draw truth tables for b and c as you have implemented them after simplification. Note that these truth tables will not have dont care entries because your implementation will produce an output value for each combination of inputs
4. Did you combine terms between outputs b and c? If so, then explain details. If not, then could you have done so?
