multiple tone meaning in English
多频声
Examples
- There are several widely used methods to acquire the frequency response graph , including single tone method , multiple tone method , noise impulse method and maximum length sequence signal impulse method
分析音频设备的频率响应特性主要有单音信号检测法、噪声冲击检测法和最大长度序列检测法等。 - It will take some real biochemical alterations on the behalf of the mineral realms for a single mineral to hold multiple tones ; however this is coming and in particular as earth climbs more greatly towards a fourth dimensional frequency in the coming 100 year cycle
为让单种矿石去掌握多重音调，矿物王国自己需要一些真实的生化改造；但是这将在未来百年周期内、尤其是当地球向第四密度频率更大攀升的时候来临。 - This article takes hanging off and wide fluctuation of transmition velocity of adsl as example , then analysis centers on the discerte multiple tone and the principle of channel load assignation . from analysis above article points out the root of adsl being sensible of noise signal . at last , reserches effects that window function and barrier effect on frequency and adopts fft to work out the noise power of adsl
本文以电信现在推出的adsl传输中链路经常掉线和传输速率经常大范围波动为例，重点分析了adsl所使用的dmt调制方式和注水算法分配信道载荷方式原理，由此指出adsl对噪声信号敏感的根源，在得到问题的根源之后，分析了窗函数和栅栏效应对频谱的影响，采用fft方法计算adsl线路的噪声功率谱，为adsl线路测试提供了可靠的理论依据。
