Description:This course is intended to introduce the student to fundamental digital instrumentation and lay the foundations for further study and applications.The module includes extensive laboratory based practical work to support and apply the lecture material.Emphasis is also placed on developing the students ability to interpret and use manufacturer’s data sheets.
Learning Outcomes:
On successful completion of this module the learner will be able to
  1. Interpret manufacturer’s data sheets of fundamental digital components.
  2. Draw circuit diagrams and explain the operation of fundamental digital electronic circuits
  3. Build and test simple digital circuits
  4. Analyse the performance characteristics of digital components
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
No recommendations listed
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Requirements
This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
