Weighted Frequency Response U
138
Special Parameter
47
allows the display
of
an Autospectrum,

or
Fre-
quency Response Function on the
upper
trace
to
be varied. The Parameter can be set
to
0,
1,

2.
0:
gives normal display
of
the Frequency Response Function
1:
displays the frequency weighting function
2:
displays the Frequency Response Function multiplied by the frequency weighting
function.
