Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function. (a) Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B. (b) Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B. (c) Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B. (d) Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B. 53.
