Reduced contribution of a nonsimultaneous mistuned harmonic to residue pitch: The role of harmonic number [PDF]
The Journal of the Acoustical Society of America, 2009 Listeners adjusted a matching sound so that its pitch equaled that of a subsequent 90-ms complex tone (12 harmonics of a 155-Hz F0), whose mistuned harmonic (±3%) was presented either simultaneously with or after the other harmonics. The third or the fourth harmonic was mistuned.

Harmonic-Reduced Bias Circuit for Ultrasound Transducers
Sensors, 2023 The gain of class-C power amplifiers is generally lower than that of class-A power amplifiers. Thus, higher-amplitude input voltage signals for class-C power amplifiers are required. However, high-amplitude input signals generate unwanted harmonic signals.
