| Abstract | In this paper we propose a design of quadband bandstop filter for the suppression of interfering signals in broadband applications. There are different approaches to implement multiband filters among which frequency transformation techniques is advantageous than other methods in terms of complexity to find the transfer functions. So it is applied here for finding the locations of poles and zeros of a direct coupled quadband bandstop filter. By properly combining several single-band filtering functions, the multiband filtering function of similar bandwidth are generated. For easy tuning, filter has been synthesized in cul-de-sac topology which eliminates the need for diagonal couplings. Finally 16-pole symmetric quadband bandstop filters have been synthesized to validate the proposed method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
