Method of and arrangement for the determination of the pitch of speech signals in a system of speech analysis, wherein sequences of significant peak positions of the amplitude spectrum of a speech signal are derived (13) from time segments of the speech signal by means of a discrete Fourier ...
125 samples long. If you take less than half that you probably don't have a long enough signal to get a reliable spectrum. You're trying to get a spectrum when some of the frequencies don't even have half a cycle in the signal. Why did you take just 50 and not ...
Given that the amplitude spectrum and the phase spectrum, taken together, uniquely describe the time signature of a signal, it is pertinent to ask how these spectra, taken separately, contribute to the signal. As a general rule of thumb, the phase spectrum is more important than the amplitude...
1)amplitude spectrum幅值谱 1.From the definition of DFT,calculation method of amplitude spectrum for digital signal is derived in this paper.根据离散傅里叶变换DFT的定义,推导出数字信号幅值谱的解析计算方法,并通过C++Builder开发工具设计了一套测试程序,对数字合成信号进行了幅值谱的计算仿真,仿真结果验证了...
real amplitude signal 的意思是：实振幅信号。双语例句 1.Results show that the saw - tooth signal amplitude oscillate within small amplitude through the calibration.通过校准,锯齿波的幅值变化量可控制在很小范围内.2.To reduce ( the amplitude of an electrical signal ) with little or no ...
aThus a carrier of frequency fc,amplitude modulated with a signal of frequency fs contains frequencies fc,fc+fs,fc-fs.The last two are called 'sidebands'.Fig.5.1 is the frequecy spectrum of an a.m.carrier. 因而频率fc,高度载体调整与频率fs信号包含频率fc, fc+fs, fcfs。最后二称‘边带’。
In physics, the amplitude of a sound wave or electrical signal is its strength. amplitude e.g. As we fall asleep the amplitude of brain waves slowly becomes greater. 进入睡眠状态时,我们的脑电波振幅慢慢变大。 2.广大;广阔;大量 Amplitude is the quality of being large in size or quantity. ...
