- To learn the concepts of network analysis in electrical and electronics engineering.
- To learn transmission lines and networks.
- To learn active and passive filter circuits
COURSE OUTCOMES: On completion of this course, the students will be able to
- Analyze an electric network using graph theory and different network theorems e.g. Thevenin’s theorem, superposition theorem, Nodal voltage etc. and power system transmission line using ABCD parameters.
- Synthesize an electric network using driving point functions
- Design active and passive filter circuits
- Explain the electrical transmission lines and verify them through experiments
CATALOG DESCRIPTION: Network Analysis and Synthesis is a field of engineering that deals with the study and applications of Graph theory, two port parameters and network synthesis, and also deals with the design and application of active and passive filters. Graph theory is considered to deal with the problems associated with large-scale electrical systems such as power transmission and distribution system. This course lay foundation for the students to study other subjects related to both the engineering streams.
