In the similar experiment, the major spectral frequency at 6.1Hz exhibits magnitude 8.71 in the original signal power spectrum of one channel (shown left), while the inner C2 tone corresponding frequency at 522.78Hz, marked line in the right spectrum, has the value of 0.17 embedded in its spectral frequency neighborhood “noise”, with the magnitude ratio over 50, consuming less than one pro mile of spectral energy.
