Describe the concept of harmonics and harmonic distortion. Illustrate your

answer with suitable annotated diagram(s).

Write on ANY TWO practical applications of feedback concepts to real-life

problems. The practical applications can be in any area, e.g. electronics,

control systems, mechanical systems, automobile systems, banking and

finance, business, economics, biological systems, medical sciences, industry,

etc.

Your answer should include a statement of the problem and how feedback

concepts are used for solving it. The answer should be supported with relevant annotated diagrams, and any useful basic equations. Elaborate

equations are not required.
