Dhanasekharan Natarajan, Electronics engineer from College of Engineering, Guindy, (presently Anna University) Chennai in 1970, obtained his post-graduate in Engineering Production (Q&R Option) from the University of Birmingham, UK in 1984. He is a Life Senior Member, IEEE (00064352) and his biography is published by Marquis, USA in their fourth edition, “Who’s Who in Science & Engineering”.He retired as Asst. Professor in RV College of Engineering, Bangalore. His earlier assignments were at Bharat Electronics and Radiall Protectron. His achievements in the industries include Application of reliability techniques for defense equipment, Root cause analysis on electronic component failures, Qualification testing of electronic components as per US and Indian military standards, Designing and implementing computerized Quality Management System, Designing software for Optical interferometer, and Design & manufacturing of lumped, semi-lumped and microwave cavity filters using self-developed software.He has authored three books and the books are published by Springer. The first book, A Practical Design of Lumped, Semi-lumped and Microwave Cavity Filters, Springer, 2013, presents the design of L-C, tubular and combline/iris-coupled cavity filters with examples.The second book, Reliable Design of Electronic Equipment: An Engineering Guide, Springer, 2015, presents the application of derating, FMEA, overstress analysis and reliability evaluation tests for designing reliable electronic equipment.The third book, ISO 9001 Quality Management Systems, Springer, 2017, explains the requirements of ISO 9001 with examples from industries. Integrating QMS requirements with ERP software is the most effective method of implementing the system in organizations. The methods of integrating QMS requirements with ERP software are illustrated with examples. A chapter is dedicated for explaining the application of Indian classic, Thirukkural, for QMS planning.

• Overview of Digital Signal Processing.- Programmable Logic Devices.- Logic Gates.- Combinational Logic Devices.- Clock and Timing Signals.
