| Abstract | This paper describes techniques which have been developed to facilitate the design of r-f multiplexers within the frequency range of 1.O to 15.0 kmc. By using techniques involving modern network synthesis, strip transmission line and waveguide filters which approximate Butter-worth or Tchebycheff functions can be easily realized. Strip transmission line filters are discussed which use tuning screws, physical variations of cavity lengths, and replaceable gaps. The waveguide filters consist of resonant cavities or resonant elements, depending on the application. Waveguide multiplexing is accomplished by using hybrid junctions, resulting in essentially no passband deterioration. An alternate technique utilizing a modified Fox type coupler in conjunction with a 3 db directional coupler is also presented. Strip transmission line 3 db directional couplers are used to multiplex the lower frequency bandpass filters. |

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.
