Digital Systems

Objectives

- Use binary number systems and binary arithmetic.
- Derive, manipulate and minimize boolean functions.
- Implement boolean functions with circuits with logic gates.
- Understand the operation of the fundamental building blocks of combinational circuits.
- Understand the operation of basic memory elements, and work with registers and counters.
- Specify and synthesize synchronous sequential circuits.
- Understand basic timing issues, including clocking, timing constraints, and propagation delays.
- Design low-complexity digital systems with both combinational and sequential components.
