Differences between Logic Function and Logic Circuit

Click For Summary
SUMMARY

The discussion clarifies the distinction between logic functions and logic circuits in digital design. A logic function is defined as an expression utilizing operators such as AND, OR, and NOT, while a logic circuit represents the physical implementation of these functions using gates like AND, OR, and inverters. Specific examples mentioned include comparators, multiplexers, adders, registers, and shifters, each possessing unique logic functions. The conversation emphasizes that each component has its own corresponding logic function.

PREREQUISITES
  • Understanding of basic digital logic concepts
  • Familiarity with logic gates (AND, OR, NOT)
  • Knowledge of digital circuit design principles

Homework Statement



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 :)



Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
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?
