查询词典 amplitude

Firstly,surd or sonant judgment with each voice frame is done,then the multi-scale wavelet analysis is done only on the sonant frames to get pitches.In order to get accurate pitches,the intervals of local modulus maxima of dyadic wavelet coefficients are corrected according to amplitude information and appearance probability information.

针对这一问题，提出一种基于小波变换的基音周期提取改进算法，将TEO算子与二进小波变换结合起来，首先进行清浊判定，然后只对浊音帧采取多尺度小波分析提取周期，提出用幅度信息和出现概率信息校正二进小波模极大值间距，从而得到准确的周期。

The output of the filter was squared in order to store the intensity of the sound rather than just the amplitude.

该过滤器的输出是平方，以存储声音的强度，而不是仅仅是振幅。

ABSTRACT: As a vector, the measurement of the sound intensity involves it's amplitude and direction.

声强是一个向量，声强测量同时涉及声强的大小和方向。

Ii For sound wave of higher energy, its intensity and amplitude are .

a 人类的耳朵对声波所传播的十分敏感。

For this purpose, the time course of the electromyogram has to be analysed, in order to detect typical fatigue-induced changes such as an increase in EMG amplitude or a shift in the spectral distribution towards lower frequencies.

对於这个目的，肌电讯号的时间轴是必须被分析的，为了检测出典型引起疲劳的改变，例如增加EMG的振幅或是转换频谱分析至较低的频率。

The authors discuss a new numerical simulation method of the downburst wind loads on the basis of the previous research. Firstly, the wind speed is expressed as the sum of an instantaneous mean wind speed and an amplitude-modulating non-stationary fluctuating wind speed. Secondly, a new method based on the modified Osegguera and Bowles/Vicroy model to simulate the mean wind is presented and the fluctuating wind is simulated by a modified spectral representation method.

在将下击暴流风速表达为时变的平均风速和调制的非平稳脉动风速之和的前提下，本文采用基于改进的OBV模型Oseguera and Bowles/Vi-croy(OBV的方法来模拟平均风速，其平均风速直接由改进的OBV模型表达，而不同于已往研究中将平均风速表达为竖向风剖面与时间函数的乘积，并采用结合快速傅里叶变化的谐波叠加法来模拟调制的非平稳脉动风速。

It also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications.

它也有一个内置的振幅包络编辑器，可定制的频谱模式和音频分析应用的频率分析窗口。

In this paper the complex scattering amplitude functions of a small metamaterial spheroid particle is derived.

摘要该文推导了异向材料小椭球粒子的复散射振幅函数。

A new method based on this relation is introduced to calculate the amplitude and position of these spurious lines.

这一结果可用于精确计算杂散谱线的幅度和位置。

Show that: the signal frequency, amplitude, when they showed at the duty cycle square wave.
