The work which is documented in this project deals with the development of front end Echo sounder receiver circuit. The goal was to develop a system which can be used for wide band applications. Receiver electronics together with the transmitter have been designed on a single board to check the performance of the complete system. The project begins with the introductory part describing about the background of Hydro acoustics and then description of various methods used in echo sounding and how they are implemented. Then, it illustrates the various options and tools available to achieve the desired goal. Design and development part provides information about how these specific methods are actually realized in practice. And at last, the developed system is tested to check the results and the concluding remarks are written.
