| Abstract | This paper describes the theory and design of a novel charge signal multiplexer (MUX) system utilizing a single charge amplifier, which is developed for multi-channel input from piezoelectric transducers. The original purpose of the design was to process charge signals from a set of tri-axial piezoelectric transducers developed for in-shoe force measurements. The goal was to reduce the number of charge amplifiers required to process multi-channel charge signals and simplify the circuit. With inputs from piezoelectric transducers, this multiplexing process results in a voltage output which is proportional to the change in magnitude of the input charge signal between samples. The multiplexed data is then acquired and reconstructed for analysis and display. In this paper, the theory, design and initial testing of an 8 channel system utilizing one single charge amplifier are described. The advantages and disadvantages of this charge multiplexer system are discussed. The results of experiments show that this charge multiplexer system is capable and suitable for multi-channel charge signal processing. |

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.
