GENERAL DESCRIPTION

The intention of this section is to provide a basic
understanding of how the DN60 operates.

In essence the function of an audio spectrum analyser
is to separate the components of any audible signal
into defined frequency bands, and to indicate the level
of energy present in each of those bands. A frequency
analysis given by the DN60 displays the overall energy
level of a signal and where that energy is distributed
through the audio spectrum (in frequency bands of 1/3
octaves) in a bar graph format.

NOTE: since frequency analysis represents the
separate components of the overall signal,
it follows that the "overall-level"
displayed should be equal to the sum of the
individual components.

The following description will be clarified by
reference to the block diagram fig. 1.
