Over the coming years, Segovia would perfect his technique and push luthiers to experiment with new woods and designs that could increase the natural amplification of the guitar.
Using the high degree diffracted waves twice, we have obtained lower noise phase difference amplification of over 100 times.
两次利用其高阶衍射可获得大于100倍的低噪声位相差放大。

SAPF, which only has better inhibition to current-type harmonic source, is not only less inhibitory to the voltage-type harmonic source, but also lead to harmonic amplification and load over current.
