What is the truth table of a 2 input gate that passes complemented data when the control input is 0?

There is supposed to be a full truth table and a simplified truth table indicating what occurs based upon the control signal.





This was my exam question and I'm still confused.What is the truth table of a 2 input gate that passes complemented data when the control input is 0?
Trick question. You were supposed to interpret the wordiness, and figure out that the question referred to a NOR gate.What is the truth table of a 2 input gate that passes complemented data when the control input is 0?
I partially agree with acetange. However, when the control input is 1 , the output would probably be a tristate. This is the case when the output of gate is in fact disconnected from the rest of the circuit. The trisate is also called a high impedance state. So the truth table becomes:





data------control--------output


---0-----------0--------------1


---0-----------1--------------Z


---1-----------0--------------0


---1-----------1--------------Z





So you see that the control will pass the complement of the input data line when it is in the 0 state but passes nothing when the control in in the 1 state.
you are saying that there are two inputs and one of which is a control input? therefore the other input should be assumed as the data input. the data input is complemented if the control is zero, otherwise th output is the same as the data input





data------control--------output


---0-----------0--------------1


---0-----------1--------------0


---1-----------0--------------0


---1-----------1--------------1
agreed with acetange....
