I am Saravanan Nanthakumar, an independent researcher in Electronics Engineering and Physics. My area of research includes Analog Design and General Relativity. Holding a master’s degree in Very Large Scale Integrated-Circuits (VLSI) Design, I am here to teach students who want to learn Electronics Engineering with detailed mathematics and its relevance to advancements in Science and Technology. I teach to ensure that the student has a clear picture of the frequency domain, as evident as how the student sees the information in the time domain. This is achieved by introducing analog/digital frequency transforms from a geometrical perspective. I do this out of the strong belief that “Hindrance to learning Electronics mostly means unclear or no picture of the frequency domain in the mind.” I make the learning/teaching process as an iteration, taking each iteration as an opportunity for improvement. Happy learning!
