The DHM method is one of the time domain numerical methods for the wave propagation in which propagation and scattering of waves are simulated as the sequences of impulses scattering as Huygens' principle states. In this paper, the DHM method is calculated by 32bit fixed point arithmetic. In the fixed point arithmetic calculation, errors caused by the overflow or the underflow sometimes occurs. To reduce these errors two correction methods are considered; one is the sign bit error detection and correction, and the other is the amplitude clipping correction. Some numerical experiments are made for the two dimensional sound field. It is shown that the errors caused by the overflow is practically reduced by the sign bit error detection and correction without increase of the circuit area.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000011678","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
