11. The middle eight sections present a softer harmonic content relative to the strident progression over the verses. 12. Some voltage optimisation devices also mitigate harmonics, reducing losses associated with harmonic content on the electrical system. 13. Nielsen studied Renaissance polyphony closely, which accounts for some of the melodic and harmonic content of his music. 14. In an online UPS system, a rectifier-DC-link-inverter is used to protect the load from transients and harmonic content . 15. The triangle has much lower harmonic content , every other odd harmonic with flipped phases every other odd harmonic. 16. Older designs of ferroresonant transformers had an output with high harmonic content , leading to a distorted output waveform. 17. Generically, the term'audio filter'can be applied to mean anything which changes the timbre, or harmonic content of an audio signal. 18. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform. 19. Most AC motors will run on MSW inverters with an efficiency reduction of about 20 % owing to the harmonic content . 20. The result is a large second-harmonic content in the resulting signal, similar to that produced by a fuzz box distortion pedal.
