Improving the Response of a Bridged-T RC Network

Abstract

The paper presents a modification of a bridged-T RC network, originally proposed by Sulzer, for increasing the stop bandwidth and decreasing the notch level in the frequency response, which also gives the facility for fine tuning the notch frequency. It uses the well-known dual input technique.

KEYWORDS:

S. C. Dutta Roy

S C Dutta Roy received his bachelor's, master's and doctorate degrees from the Calcutta University and served the River Research Institute,West Bengal, the University of Kalyani and the University of Minnesota, USA, before joining the Indian Institute of Technology Delhi (IITD). He was with the IITD for more than four decades in various capacities – first, as professor of electrical engineering, head of the department and dean of undergraduate studies, and after superannuation, as IITD emeritus fellow, Indian National Science Academy (INSA) senior scientist and INSA honorary scientist. He has held visiting professorships at the University of Leeds, UK and the Iowa State University, USA. Currently, he is an INSA honorary scientist working from home with active research interests in circuits, systems and signal processing. Professor Dutta Roy is the recepient of many awards and recognitions, including the Shanti Swarup Bhatnagar Prize, Vikram Sarabhai Award, Pandit Jawaharlal Nehru Award, Fellowship of the IEEE and of all the national academies in science and engineering, and distinguished fellowship of the IETE. What he values most, however, is the love and appreciation of his large number of direct as well as virtual (through NPTEL lectures on the internet) students and professional colleagues spread throughout the world. Besides the subjects of his research interests, he maintains a deep interest in Indian Classical Music.
