查询词典 waveform digitization

Theoretically, for quasi-periodic audio signals, we can use the waveform within a fundamental period as the timbre of the frame.

直觉来看，音色的不同，代表基本周期的波形不同，因此我们可以使用基本周期的波形来代表音色。

We now have to make some assumptions about the characteristic of the jitter to proceed. One assumption that seems to work is that the jitter amplitude has a Gaussiandistribution. For a jitter waveform that has a Gaussian distribution, there is a point on the Gaussian jitter distribution curve that reflects the RMS value of jitter for Gaussian distribution waveforms, just as with the wave.

一个可行的假定是Jitter幅度具有高斯发布，对于有高斯发布的Jitter波形，高斯Jitter分布曲线上有一点反映了Jitter在高斯分布波形下的RMS值，这点称为"1-sigma值，标准分布"或者"RMS Jitter"值。

B Through theoretical and experimental studies, the paper investigats the relationships between hammer geometer and stress waveform generated by the hammer. After the mechanical meanings of linear model used by others are demonstrated, a simple expression of rigidity of an equivalent spring for direct impact between a hammer and a rod is obtained. Based on the above work, a mathematical model and numerical method for the impact of the hammer with progressively changing cross-section on the rod are presented.
