Display of Sound Spectrographs in Real Time
Abstract
A technique is described for displaying sound spectrographs in real time. The patterns are obtained by scanning the rectified output of a bank of filters and feeding the output into a standard PPI oscilloscope from a radar system. Thus, no specially constructed visual display unit is required. A method of changing the frequency resolution of the patterns so obtained is described.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
