3.2.1.4.2. Pink noise generation.
Pink noise is a random noise that contains the same energy quantity per
octave, this means that, the energy of this kind of signal decrease 3 dB every
time the frequency increases one octave, in such a way that, as every upper
octave contains double frequency and half energy, the frequency response of a
pink noise. Measured with a spectrum analyzer, the signal should appear flat
Pink noise has several applications, for example, among others, room
equalization or checking of proper working of sends to speakers.
To generate this kind of signal press “Select“ (12) from any channel. The “Test
Signal Generation“ is selected by the rotating encoder (21) placed on the right
of the main display. Next the “Pink Noise“ is selected in the same way as shown
in the following screen :
Pink noise levels are
adjusted in this screen, by
rotating encoder (21) and
will activate or deactivate
the pink noise signal.
Pressing under “RESTORE“
will restore pink noise
parameters to the minimum
level that appears by
default. Press “EXIT“ to
leave this screen.
3.2.1.4.3. White noise generation.
White noise is a random noise that contains the same energy quantity in each
frequency, with a one hertz bandwidth. This means that every tone contains the
same energy as the next one., If this signal is analyzed with a spectrum
analyzer, it will show a rise of 3 dB per octave.
To generate this kind of
signal press “Select“ (12)
from any channel. Then
select “Test Signal
Generation“ by rotating
encoder (21), placed on
the right of the main
display. Next select, in the
same manner “White
Noise“ and the following
screen will appear:
White noise levels are adjusted in this screen, by a rotating encoder (21).
Pressing under “ON/OFF“ (22) will activate or deactivate the white noise signal.
Pressing under “RESTORE“ will restore white noise parameters to the minimum
level that appears by default. Press “EXIT“ to leave this screen.
