It will affect the original signal.
No information is lost and the original signal can be reconstructed.
Attenuation- loss of the original signal properties.
Once this happens the original signal is no longer recoverable.
Electromagnetic interference can degrade signals and make the original signal impossible to extract.Combinations with other parts of speech
As mentioned earlier, each sample represents a point of the original signal.
Tribole thinks ignoring these primal signals is a dangerous practice.
The reflected signals arrive at the receiver later than the primary signal.由此,该对中的一根线传输原始信号,另一根传输其反向副本。
With that, one wire of the pair transmits the original signal and the other one transports its inverse copy.原始信号x[n]首先通过一个半带高通滤波器g[n]和一个半带低通滤波器h[n]。
The original signal x[ n] is first passed through a half band high-pass filter g[ n] and a low-pass filter h[ n].如果一个delta函数是原始信号,则作为时间反演镜的传感器接收的信号就是这个频道的脉冲响应。
If a delta function is the original signal, then the received signal at the TRM is the impulse response of the channel.镶边(flanger)-一个延迟信号被加到原始信号上,其延迟连续变化(通常小于10ms)。
Flanger- a delayed signal is added to the original signal with a continuously-variable delay(usually smaller than 10 ms).通过减少原始信号速率的1⁄4或1⁄2,传输速率分别下降到2.5或5Gbit/s。
By reducing the original signal rate to 1/4 or 1/2, the transfer rate drops to 2.5 or 5 Gbit/s, respectively.镶边(flanger)-一个延迟信号被加到原始信号上,其延迟连续变化(通常小于10ms)。
Flanger- to create an unusual sound,a delayed signal is added to the original signal with a continuously variable delay(usually smaller than 10 ms).因为没有授权的用户不知道扩展原始信号的扩频因子,所以他们无法解码。
Because non-authorized listeners donot have the key used to spread the original signal, they cannot decode it.合唱(chorus)-一个延迟的信号被加入到原始信号中,延迟是固定的。
Chorus"- a delayed signal is added to the original signal with a constant delay.对每一位都进行了编码,这样接收器就可以在接收到这些位时重组原始信号。
Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.它的物理意义在于电磁波沿传输线传播,通常会有反射成分干扰原始信号。
The physical significance of this is that electromagnetic waves propagate down transmission lines and in general,there is a reflected component that interferes with the original signal.当增加的点越来越多时,复现原始信号的能力就提高了。
As more and more points are added, the ability to replicate the original signal improves.回声(echo)-一个或者多个延迟的信号加入到原始信号中。
Echo- one or several delayed signals are added to the original signal.如果相互交叠(这种现象称为混叠),就不可能再从采样信号中恢复出原始信号。
If they do(a phenomenon called aliasing),we can no longer extract the original signal from the samples.但请记住,比Vin值大得多的值将导致代表原始信号的量化级别更少。
Bear in mind, however, that a value much larger than the value of Vin willresult in fewer quantisation levels representing the original signal.然后,可对原始信号进行后处理,以了解检测到的故障类型及其严重性。
The raw signal can then be post-processed to find out what type of fault has been detected and its severity.但是,如果才能是一个过程,可以由原始信号启动,那么PS233成功的原因就一目了然了。
But if talent is a process that can be ignited by primal cues, then the reason for PS 233's success is clear.这种原始信号在随后的可能通过仪式化不断演化,变成一种情绪以及身体痛苦的象征。
This primal signal may have later evolved through ritualization to become a sign of emotional as well as physical distress.原始信号与目标接收到的信号的频率差随着距离的增大而增加。
(The difference in frequency between the initial signal and the one received from the target increases with distance.).过去,这种复杂性一直是系统尝试定位原始信号的障碍。
In the past,this complexity has been an obstacle for systems trying to locate the origin of a signal.有若干个因素会影响信号的精度,其中最主要的是原始信号中的噪声以及信号处理过程中混入的噪声。
A number of factors affect how precise a signal is,mainly the noise present in the original signal and the noise added by processing.这就是傅里叶变换:它的作用是能精确地揭示原始信号包含着哪些频率。
That is the Fourier transform:a function that explains exactly what frequencies lie in the original signal.
If the value of the original signal exactly matches one of the predefined values everything is good.
