Module contents

● Introduction to digital technology and combinational and sequential logic.
● Number systems (binary, hexadecimal, representation of negative numbers (single, two's complement), arithmetic with negative numbers)
● Logical functions and tags: INV, AND, OR, NAND, NOR, XOR
● Combinational logic: logical operations, combinational logic
● Truth table and combinational basic circuits: Half/full adders, subtractors, multiplexers and demultiplexers, decoders (e.g. BCD => 7-segment).
