Compensation
There is no need to compensate frequency
characteristics if they are flat (no peaks or
valleys) when you have measured the
frequency characteristics with a measuring
device. However, sometimes the frequency
characteristics rise or fall in some places. If this
happens, the frequency characteristics must be
compensated. Create a frequency curve having
characteristics that are opposite to the center
frequency of parts where the characteristics rise
and fall to cancel out these peaks and values,
and make the frequency characteristics as flat
as possible.
Making the frequency characteristics as flat as
possible is called "Compensation".
