Example of the spectrum and acoustic waveform for three different acoustic signals that have the same pitch (100 Hz).
A. Harmonic complex tone: composed of the 1st (fundamental), 2nd, and 3rd harmonic, each with randomized phase.
B. Repeated broadband noise burst (100 Hz repetition rate).
C. Missing fundamental harmonic complex tone: composed of the 2nd, 3rd, and 4th harmonic, all in cosine phase.
