Concept:

Signals that enter a device are inputs, while the signal that leaves it is the output.

Explanation:

From the diagram,

X

and

Y

enter the device.

X

and

Y

carry incoming signals and are therefore input signals.

Z

leaves the device as the final result.

Therefore,

Z

is the output signal.

Hence, the order is

X =
