JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech III INTRODUCTION TO MECHATRONICS Previous Question Paper (November/December - 2018 - R16)
Part A is compulsory (25 marks). Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit (10 marks each).
Part A
Define mechatronics.
Answer
Mechatronics is the synergistic integration of mechanical engineering, electronic engineering, computer technology, and control systems in the design and manufacture of products and processes to create more functional and adaptable systems.
Classify the filters and explain in brief.
Answer
Filters are classified based on the frequency range they allow to pass: Low-pass filters allow signals below a cutoff frequency to pass, High-pass filters allow signals above a cutoff frequency to pass, Band-pass filters allow a specific range of frequencies to pass, and Band-stop filters attenuate a specific range of frequencies.
