Course Outcomes:

At the end of the course the student will be able to:
• CO1: Use Laplace transform and inverse Laplace transform in solving differential/ integral equation
arising in network analysis, control systems and other fields of engineering.
• CO2: Demonstrate Fourier series to study the behaviour of periodic functions and their applications in
system communications, digital signal processing and field theory.
• CO3: Make use of Fourier transform and Z-transform to illustrate discrete/continuous function arising
in wave and heat propagation, signals and systems.
• CO4: Solve first and second order ordinary differential equations arising in engineering problems
using single step and multistep numerical methods.
• CO5:Determine the extremals of functionals using calculus of variations and solve problems
arising in dynamics of rigid bodies and vibrational analysis.
