Is it me not understanding this table and diagram or something? If in a Moore machine, the output only depends on the current state Then why does the table for states F and H say the output is independent of the input? At F, if the input is a 0 the state changes to I and output would be a 1 At F, if the input is a 1 the state stays the same at F and the output would be a 0
The state table does not reflect this?
The state table should show multiple outputs...

Because if it depends only on the current state, then it can't also depend on the inputs.
The inputs determine whether you get to a certain state. But after you're in that state the output only depends on the state. Assuming a typical clocked design, the output doesn't change instantly if the inputs change before the next clock edge. And it only changes at the clock edge if the changed inputs lead to a new state.
True to say "In a Moore machine the output only depends on the current state". In a Moore machine the output will not respond to a change in the input until the next clock pulse when the state moves to the next state (a new present state). Therefore a Moore machine only has one possible output during each present state.
In a Mealy machine the output will respond immediately (almost) to a change in the input and therefore can have more than one possible output during each present state.
To summarize - The output of the Mealy machine is a function of both the current state variable and the input variable whereas the output of a Moore machine is only a function of the current state variable.
