Hi everyone

For the input

**F(A,B,C,D)={1,4,5,7,9, 11, 13, 15}**

i got the truth table & K-map as below:

Truth table(Z is the output):

**ABCD Z**

0000 0

0001 1

0010 0

0011 0

0100 1

0101 1

0110 0

0111 1

1000 0

1001 1

1010 0

1011 1

1100 0

1101 1

1110 0

1111 1

Z = A’B’C’D + A’BC’D’ + A’BC’D+ A’BCD+ AB’C’D+ AB’CD+ ABC’D+ ABCD

K-map

**CD/AB 00 01 11 10**

**00 **0 1 0 0

**01** 1 1 1 0

**11** 0 1 1 0

**10 **0 1 1 0

how do i simplify it? is it possible to eliminate the C input from the eqn?I need to

**Design a 8:1 multiplexer capable of implementing the logic function below:**

**F(A,B,C,D)={1,4,5,7,9, 11, 13, 15}, using ABD as the select inputs**

thank you for guiding & helping....really urgent...tq..
