    Abstract
    The sparker echo signal had been recorded along with the EPC recorder trigger on audio cassettes in a dual channel analog recorder. The sparker signal in the analog form had to be digitised for further signal processing techniques to be performed on it to classify the seafloor sediment properties. A specific purpose oriented programmable delay circuit was developed to generate the necessary delay so that the A/D conversion could start just before the arrival of the echo from the water bottom interface
