India has its position in the global technological arena as the most preferred destination for developing technology and its enabled services. To realize the goal of capturing a slot among the top five economies in the near future, we need to become a major player in Information and Communication Technology development. This would be possible through research and development taking centre stage in industry and technical education.Most of the Technical Institutions have realized the situation, the sheer size of the economical demands and have started involving in the development of the technology. Bannari Amman Institute of Technology (BIT) is celebrating its Silver Jubilee this year and is actively promoting research and development through UG, PG and Ph.D programmes offered in the Institution. In BIT, National and International Conferences, Workshops, Seminars, and Faculty Development Programmes are organized in the major areas of Engineering and Technology. In continuation of this process, the Departments of Electronics & Communication Engineering, Electronics & Instrumentation Engineering and Electrical & Electronics Engineering organized the First International Conference on Circuits, Signals, System and Securities 2020 (ICCSSS 2020).We are pleased to present the proceedings of the ICCSSS 2020 and we sincerely hope that all participants and interested readers would be benefited from this proceeding. Therefore, it is a great pleasure and beneficial for all to take this advantage and build strong sustainable network among researchers. It provides a platform for the scientists, researchers, scholars, engineers, students as well as marketing professionals from all over the world to share their experiences, cases and ongoing research activities through presentation, discussions and publications. The aim is to foster research relations between academia and the industry, for the presentation and exchange of their thoughts and practices in various domains.ICCSSS focuses on Signal Processing, Image Processing, Communication, Machine Learning, Security System, Automation Technologies and Power Conversion. The conference comprises of three key-note speeches by eminent academicians and paper presentations by the faculty/research scholars/students from various Universities and research centres. The selected papers for this publication are further classified into ten topics viz. Machine Learning, Deep Learning, Communications, Networks, VLSI Design, Process Control, Embedded System, Electric Drives, Internet of Things and Network Security.Nearly 298 articles were received from various states across India and other countries. After review by experts from academia and industry, 129 papers have been selected for presentation and publication in the proceedings.This conference proceedings will serve as a reference material and would be recommended for the libraries. This compendium of latest research articles will be highly beneficial for the academicians, scholars, industry researchers and policy makers who are keen in observing the latest trends in engineering and technology towards product/service/policy formulation. In this regard, we anticipate a good welcoming opportunity for this title to get exposed and popularized, especially through the banner of IOP Publications.On behalf of the organizing committee and the host Institute, we thank all the contributing authors, members of various committees, technical reviewers, and co-editors to make this attempt a grand success.List of Editors, TECHNICAL ADVISORY COMMITTEE are available in this pdf.
