●About correction
When the frequency characteristics are measured by a measuring device, they do not need to be corrected if the frequency characteristics are flat (no ridges or valleys in the frequency waveform). However, frequency characteristics sometimes partially rise up or fall down. If this happens, create a frequency curve of inverse characteristics matched to the center frequency of the ridges or valleys in the frequency waveform. This corrects the frequency characteristics so that they are flat.
"Correction" is the process or making frequency characteristics as flat as possible.
Flat frequency characteristics can be made by selecting a
