    Abstract
    Transmultiplexer is one of the applications of Filter banks, which is used to transmit many signals simultaneously through a single channel and so that to separate at receiving end. Design of transmultiplexer using prototype filters (low pass filters and band pass filters) has been studied and analysed with respect to complexity. Transmultiplexer design using complexity efficient polyphase structure has been studied and analysed in this thesis. In this thesis, different complexity efficient structures better than polyphase using CIC based structure, multistage CIC based structure, two stage CIC based decimator and multistage CIC based structure with compensator have been proposed. Performances of proposed structures are analysed (analysis of pass-band fluctuation, stop-band attenuation of each filter in transmultiplexer) in MATLAB environment with different classes of input like speech and image. This thesis also considers complexity of proposed structures.
