Enhancing the Response of Two Second Order RC Networks

Abstract

We present, in this short communication, a method for enhancing the bandpass/bandstop response of two second-order RC networks. In the process, we also show how single grounded resistance control of the resonance/notch frequency can be obtained.

KEYWORDS:

• Bandpass response
• Bandstop response
• RC networks

Notes on contributors

S. C. Dutta Roy

S C Dutta Roy was educated at the University of Calcutta, obtaining the DPhil degree for research on Network Theory and Solid State Circuits in 1965. He served the River Research Institute, West Bengal, as a research officer for two years, the University of Kalyani as a lecturer for four years, and the University of Minnesota, USA, as an assistant professor for three years, before joining the Indian Institute of Technology Delhi (IITD) as an associate professor in 1968. He was promoted to a full professorship in 1970, and served the IITD for more than four decades in various capacities – as head of the Department and dean of Undergraduate Studies while in active service, and after superannuation in 1998, as IITD Emeritus Fellow, Indian National Science Academy (INSA) senior scientist and INSA honorary scientist. Currently, he holds the title of INSA emeritus scientist. He has held visiting professorships at the University of Leeds, UK and the Iowa State University, USA for one year each, on sabbatical leave. He still maintains an active research interest in circuits, systems and signal processing, and still publishes research papers on these topics. He has published two books, entitled Circuits, Systems and Signal Processing (Springer, 2008) and Topics in Signal Processing (Springer, 2009) and more than 250 research papers in IEEE, IEE and other high SCI impact paper journals. Professor Dutta Roy is the recipient of many awards and recognitions, including Honorary DSc degrees from the Indian Institute of Science Education and Research, Shibpur, and the Dayalbagh Educational Institute (Deemed University), Agra; national prizes, including those named after Shanti Swarup Bhatnagar, Vikram Sarabhai, and Pandit Jawaharlal Nehru; Fellowships of the IEEE and of all the national academies in science and engineering; and Distinguished Fellowship of the IETE. He is the winner of the IEEE Signal Processing Society Distinguished Teacher Award for the year 2021. What Professor Dutta Roy values most is the love and appreciation of his large number of direct as well as virtual (through NPTEL video lectures on YouTube) students and professional colleagues spread throughout the world. Besides the subjects of his research interests, he maintains a deep interest in Indian Classical Music.
