#### Training objectives

Knowledge. Boole Algebra, numbering systems, binary numbers and correlation with Boole Algebra. Combinatory and sequential digital electronic circuits, from base logic gates to more complex device like counter and registers and other general digital application. Schematic functionality and programming of microcontrollers.

Ability. Understand the behavior of a general digital circuit by analisys of single components. Design and simplify of digital circuit. Design of firmware for microcontrollers.

#### Prerequisites

Elementary mathematics.

#### Course programme

Fundamental logical gates, main principles of Boole's algebra. Truth tables; logical variables and functions. Reduction of logical functions by mean Karnaugh's maps. Universal gates and their applications. Combinatorial and sequential circuits. Decoders and converters. Flip Flop Set Reset, JK, counters and comparators. Totem Pole, Open Collector and Three state outputs. Bus comunication. Multiplexers and demultiplexer. Development of simple circuits : data input by keyboard, circuit to realize sum and subtraction between 2 binary words, bus comunication, measurements of time and frequency of TTL signals. Comparators, shift registers and counters. Replication of simple digital circuits with firmware for microcontrollers.

#### Didactic methods

Theory and practice experiences.

#### Learning assessment procedures

A general overview about theory and understanding of digital circuits will be evaluated with a written test.
Ability in designing digital system and microcontroller firmware will be evaluated with a final laboratory project during final part of the course.
To complete the evaluation an oral exam will be oriented in a discussion about written test, final project and some arguments treated in the course.
