A new portable stand alone digital processor

The characterisitics and applications of a new digital processing instrument, particularly useful for speech, underwater acoustics, and noise analyses, will be described. Special emphasis was placed in the design to permit transient capture analysis, viewing of both the time function and its spectrum and the presentation of all information, together with the status of the analyzer on a built-in oscilloscope. Small size and portability have been achieved in an instrument the size of a small overnight suitcase by employing digital processing and the combination of hardware and programmed logic.
