Comparing the frequency analyses 300 and 1500, the signal processing system 700 spreads the spectrum of harmonic frequencies for the low level input signal x and, thus, reduces peak energy levels by 9 dB, 12 dB, and 13 dB for the respective 3rd, {HEAD ~ 5th}, and 7th harmonic frequencies of {TAIL ~ a fundamental harmonic frequency} of 384 kHz
