## Course overview ### Number systems * Expressing numbers in binary, decimal, hexadecimal * Negative numbers in binary * Simple binary codes * Binary coded decimal
### Boolean Algebra * Theorems of Boolean algebra * Simplifying Boolean expressions * Important algebraic forms like Sum-of-products and Product-of-Sums.
### Digital Circuits * Circuit Analysis and design * Using AND, OR and NOT gates. * Using NAND and NOR gates. * Minimum cost design of circuits using Karnaug maps. ![](./2022-08-29-what-to-expect-from-the-course_files/combinational-circuit.png)
### Digital Circuit modules * Digital adders, subtractors * Encoders and decoders * Multiplexers
## Sequential vs Combinational systems ![](images/switching-network.svg) * *Combinational systems*' output is a function of present inputs only (no memory)
