A logic function is just an expression using operators {AND, OR, NOT}.
A logic circuit is basically the drawing corresponding to the function using the gates
AND and OR and the inverter.

Thank you Max for answering my question.. So you mean, all of them like Shifter and Register have their own logic function?
