The Conventional Wien Network for Single-Component Frequency Control

Abstract

The well-known Wien network is redesigned here for single-component frequency control, by using a potentiometer to substitute the two fixed resistances. The network is analyzed and the frequency of peak and the peak value are derived and discussed.

KEYWORDS:

• Wien network

Notes on contributors

S. C. Dutta Roy

Suhash Chandra Dutta Roy was educated at Calcutta University, culminating in a DPhil degree in 1965. He served the River Research Institute,West Bengal, as a research officer for two years, the University of Kalyani as a letcturer 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 professor in 1970 and served 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 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.

Professor Dutta Roy is the recipient of many awards and recognitions, including the Shanti Swarup Bhatnagar Prize; 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.
