Function block diagram

About this function block diagram

Function block diagrams are useful in digital logic design. They make it easy to define and understand a circuit or part of it. The function block diagram of an xor gate reveals how it can be developed directly from more basic gates.

This block diagram shows how input travels through the building blocks of an xor gate. To provide an inverted input signal, the inputs are first fed into not gates. These inverted signals, together with the original inputs, are then inputted to gates. The result is passed through or gate to get the whole xor operation done.

These types of block diagrams are particularly helpful for engineers and students. They compound simpler forms of logic functions into forms that can be analyzed and evaluated more easily concerning the simpler forms.

Studying this function block diagram of the xor gate will teach novice learners its logic and how it works. This shows how some of the simplest functions that exist in digital circuits can be used to form other more complex functions.
