Equipment and components used in cabled distribution systems primarily intended for television and sound signals general specification for frequency modulated stereo and monotonic modulators 电视和声音信号的电缆分配系统设备与部件调频立体声和单声道调制器通用规范
Eureka 147 employs both 48khz and 16bit sampling rates for audio playback . the signal is then compressed with mpeg1 - layer 2 technology . the system allows a flexible range of frequencies between 64 - - 192 kbps for mono channels 2mbps的数据；声音的运算是使用48khz和16bit采样率，然后用mpeg1 - layer2的方式来压缩，若作单声道的广播，系统可容许弹性地使用64 - - 192kbps的速率，普通情
Proposed by the european broadcasting union , eureka 147 is widely applied in europe , canada and part of asia . the technology operates in the new l - band or vhf band iii . its 1 . 5 mhz bandwidth can accommodate a maximum of about 1 . 2 mbps of data Eureka 147是现时欧洲广播联会european broadcasting union推广的制式，被欧洲加拿大和部份亚洲地区所采用，它的设计是需要另外在新的频带或甚高频带vhf band iii操作，频宽1 . 5mhz ，最大可传送约1 . 2mbps的数据声音的运算是使用48khz和16bit采样率，然后用mpeg1 - layer2的方式来压缩，若作单声道的广播，系统可容许弹性地使用64 - 192kbps的速率，普通情
At the beginning of this thesis , we introduce the fundamental of the acoustics and the perceptual mechanism . next , different kinds of speech processing methods including time processing and time - frequency analysis are presented , such as short time average energy , short time cross zero analyses , short time autocorrelation function analyses and fft . at last , we focus on the sound separation , especially on single channel sound separation 在这篇文章开始的部分,我们介绍了声学的基础知识和人类声音感知的机理;接下来,我们给出了在时域处理和频域处理语音信号的一些经典的技术,比如短时平均能量分析、短时过零分析、短时自相关函数分析、快速傅立叶变换等;本文重点从理论和实验上讨论语音分离,特别是单声道语音分离的算法及其在分离音乐鼓点中应用。
