| Abstract | In this paper we present a PDA-based fetal heart monitor that is able to provide instantaneous fetal heart rate (FHR) for the pregnant women. A modified spectral subtraction algorithm is first used to remove the unwanted stationary background noise from the noisy fetal heart sound. The AM/FM modulation technique is then employed to make the fetal heart sound more audible so that both pregnant women and gynaecologists can identify the rhythmic fetal heart beat sounds easily. A real-time algorithm is proposed to extract the fetal heart rate information from the weak and noisy signals. Furthermore, based on the signal spectrum distribution, a confidence factor (CF) is designed to indicate the reliability of the estimated fetal heart rate in real time. The device has been tested in a local hospital on a sample group of 41 pregnant women. Our finding shows that an approximate 75% of the pregnant mothers are able to hear their baby's heart sound clearly using our device. Tests are also carried out to compare the fetal heart rate calculated using our device and the existing ultrasound cardiotocography (CTG) machine. In most time our device functions properly and provides results close to the CTG records |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
