1. If possible, it will also be tuned to the third harmonic , which is G-sharp. 2. The third harmonic of the AC signal reveals heating and temperature fluctuations of the material. 3. The " harmonic finger " can also touch at a fifth higher ( a third harmonic ). 4. The second harmonic is the first overtone, the third harmonic is the second overtone, and so on. 5. At the end of the year, Jason Hughes also released an album with the band Third Harmonic Distortion. 6. This is particularly the case for the third harmonic , which causes a sharp increase in the neutral conductor. 7. Neodymium glass solid-state lasers are used in extremely high power ( third harmonic at 351 nm in laser fusion devices. 8. The third harmonic of the pilot ( 19 & times; 3, or 57 kHz ) is used for Radio Data System. 9. A further bonus was that third harmonic distortion was much reduced relative to a comparable pentode ( Terman pp 198 9 ). 10. The quarter wave resonance was calculated to be 1780 Hz, while the measured fundamental was 1625 Hz with detectable second and third harmonics .
