#9) You are to implement the following function F(A,B,C,D,E,F) which outputs a 1 whenever the binary number represented by ABCDE is ODD and 0 otherwise. A is the MSB and E is the LSB. Draw the function F(A,B,C,D,E,F) and show the work that led you to that answer. Since I am not so sadistic as to have you draw the truth table of a 6 variable function and draw the K-map of such a function, you should realize, as a...
