4. Graph window
The graph displays the changes in processed signal levels over time and moves at constant
speed from right to left.
The graph
shows processed signal
- in mode
- change in the level of processed valid signal over time
- in modes
,
and
- change in the level of current signal value over time
Narrow scale
Displays the level of input signal.
A filled upscale signifies input overload.
Overload can be eliminated and he
optimal level of input signal can be set
by using the
/
Figure
Displays the level of processed signal
- in the mode
valid value of the signal
- in the mode
- current value of the signal
- in the mode
and
maximum current value of the signal for the previous second (pulse amplitude)
5. Acoustic signal spectrum window
It displays the spectrum of the filtered signal.
When working with EMD switching the window can have the following view :
Fig. А.4
Fig. А.5
dark segments
correspond to the frequency
components of valid
(«continuous») signal
light segments
correspond to frequency
components of accidental
interference
Band pass of the filter on the figure - 0,21…0,95kHz. It is possible to switch over
to adjusting the image scale at vertical by means of
▲/▼
and volume in headphones
by
◄/►
. it is possible to switch over to adjusting the pass band and vise versa by means of
(
→◄/►→
).
The frequencies at which light segments significantly predominate over dark probably are the
interference frequencies to be suppressed by the band pass filter.
