| Abstract | This paper presents a new signaling scheme called PWAM (pulse width and amplitude modulation) to obtain the optimum combination of bandwidth and performance of the serial link transceiver design by combining the conventional PWM(pulse width modulation) and PAM(pulse amplitude modulation) approach in the wire-line data transmission. For the number of voltage level M and the number of different pulse width N, the maximum bit rate of PWAM-(M x N) scheme improves to log2M + log2N times the symbol rate while the maximum bit rate of PAM-M and PWM-N are log2M and log2n times the symbol rate, respectively. Jitter analysis for PWAM scheme has been performed based on the low pass characteristic of the wire-line communication channel. Novel techniques are also proposed to compensate the channel loss of different symbols. The simulation demonstrates the effectiveness and novelty of the proposed scheme. |

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.
