2 credits

 

The objective of this Course is to provide the students with an introductory and broad treatment of the field of Electronics Engineering to facilitate better understanding of the devices, instruments and sensors used in Civil Engineering applications. Lab should be taken concurrently. This course emphasizes more on the laboratory/practical use of the knowledge gained from the course lectures.

 

What Will I Learn?

a)                    Know broadly the concepts and functionalities of the electronic devices, tools and instruments

b)                    Understand use, general specifications and deployabilities of the electronic devices, and assemblies

c)                    Confidence in handling and usage of electronic devices, tools and instruments in engineering applications
