| Abstract | We discuss a new technique to control the resonant frequencies of a straightedge magnetostatic wave (MSW) resonator without changing the external magnetic field intensity and the circuit parameters of a feedback load circuit. The method is to use multiple microstrip electrodes at the edges of the resonator and PIN diodes are connected to each electrode in series. Upon switching each PIN diode on or off, various incremental changes of the input admittance at the center electrode can be realized while the oscillation condition is sustained. Theoretical investigation reveals that very large and incremental resonant frequency shifts can be obtained. This indicates a possibility of digitally coded control of the resonant frequencies, which may be useful in mobile telephone applications. The possibility of the new technique was verified by a preliminary experiment |

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.
