Abstract : This patent discloses an apparatus for extracting, storing and repetitively replaying a broadband datasample is fabricated from proven electronic components to assure long term reliability and reproducibility. A broadband acoustic signal is digitized and stored in a RAM until it is loaded with the desired signal. An adjustable clock controls the rate at which the stored signal is loaded and repetitively displayed so that it spectrum and characteristics can be fully analyzed. Appropriate filters are provided on the input and output sides to block incoming signals outside of the range of interest and those signal components attributed to the variable clock. Selection of particular portions of the stored desired signal may be addressed for detailed analysis on a repetitive basis if needed. Thus, any portion of a continuous broadband acoustic signal may be selected for storing and repetitive cycle analyses without introducing distortion that might otherwise be attributed to conventional approaches relying upon mechanical reproduction and recycling devices.
