Objectives
escribe digital systems through combinatorial Boolean algebraic expressions, truth tables, and schematics. Apply methodology for synthesis of combinational circuits. Convert numbers between different base numbering, such as decimal, binary, hexadecimal and octal. Analyze methods of modular decomposition of combinational circuits, including circuits for binary arithmetic. Apply techniques for expeditious design of counters. Apply methodology for synthesis of synchronous state machines, starting from state diagrams. Implement digital systems with low/medium complexity using its decomposition

Teaching method
Contact with students is accomplished in two lectures of 1h30min each (3 hours / wk.) and one lab class (3 hours / week).
The lectures are classes where exposure promotes discussion of topics, allowing emphasizing different aspects at conceptual and technological levels.
The laboratory classes allow integration of different emphasis on several aspects, such as problem solving, the use of computational tools for simulation and synthesis of digital systems, and physical experimentation by implementing digital circuits using discrete elementary circuitry as well as programmable logic devices
