Differences between Logic Function and Logic Circuit

  1. Mar 4, 2012 #1
    1. The problem statement, all variables and given/known data

    The task required me to find the logic function / circuit for :

    a. comparator
    b. multiplexer
    c. adder
    d. register
    e. shifter

    So what are the differences between logic function and logic circuit?
    Thank you :)

    2. Relevant equations

    3. The attempt at a solution

    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?
