Kursinnehåll

In this MOOC we will cover the basic properties of digital components such as logic gates, latches and flip-flops. The aim is to impart both the mathematical tools and the practical understanding to be able to build and dimension (digital) circuits independently. For this purpose, calculation, simulation and practical examples are available.

The course is divided into five parts:

1. CMOS Circuits
2. Multivibrators
   • Bistable Multivibrators
   • Monostable Multivibrators
   • Astable Multivibrators
3. Analog-to-Digital Converters
4. Digital-to-Analog Converters
5. Hardware Interfaces

Kursmål

The learning objectives of the individual sections are divided into four learning objective taxonomy levels and are detailed again in the respective sections. For the sake of clarity, only the learning objectives of the higher taxonomy levels are listed here.
