An overall value refers to a total of the frequency band powers of the analyzed power spectra. That is, it is the power value (mean square value) of the time signal prior to the analysis. Refer to the related item for the method of calculating the overall values with the FFT analyzer.

In the calculation of an overall value, it must be noted that the value is a total of the power (equivalent to V2) of each band of the power spectrum, not a total of linear spectrum values (equivalent to V).

The FFT analyzer of ONO SOKKI always displays the overall value with the ◄ mark at the right end of the power spectrum graphic display.
