查询词典 Signal-to-Noise

In digital signal and image processing and digital communications, a continuous signal is usually represented and processed by using its discrete samples.

在数字信号和图像处理以及数字通信中，一个连续信号通常用它的离散采样表示。

The relay is driven by a pulsed signal instead of a continuous signal.

这种继电器驱动而不是一个连续信号脉冲信号。

Time domain signal is continuous signal, with continuous time Fourier transform as discrete signals, discrete-time Fourier transform.

当时域信号为连续信号时，用连续时间傅里叶变换；为离散信号时，用离散时间傅里叶变换。

From the most basic signal analysis, digital signal processing, and the Fourier transform convolution theorem was derived and that, and with MATLAB simulation.

本文从最基本的信号系统分析、数字信号处理过程开始，对傅里叶变换以及卷积定理进行了推导和证明，并且用MATLAB进行仿真。

This paper introduced that how resynthesize the neural firing rate by correlogram inversion,how resume the lost information by half wave rectification inversion.and a solution of speech enhancement based on masking properties of human auditory is proposed and implemented,we can not only analyse and resynthesize speech signal ,but also analyse and resynthesize speech signal in noisy entironment with the system.

又根据听觉生理特点提出了抗噪声方案，使我们的语音分析／重构系统不仅可以对无噪信号进行重构，而且还可以在噪声环境下的语音信号进行重构。

As response signal of damped free vibration could be considered as product of the harmonic wave and the unilateral exponential function and the rectangle window, the peak frequency and phase are frequency and phase of the harmonic wave signal is proved in theory in this paper.

针对自由衰减振动信号的连续谱，将其看成无限长谐波信号与单边指数函数及矩形窗的乘积，在理论上证明峰值点的频率和相位就是信号的实际频率和相位。

The main work of this paper is composed of three parts: the first one is the normal Kalman filtering for the signal of Global Positioning System; the second one is the extended Kalman filtering for the signal of Dead Reckoning; the last one is the information fusion between GPS and DR.

本论文的工作主要分为三大部分：第一是对全球定位系统的信号进行标准的卡尔曼滤波，第二是对航位推算的信号进行扩展的卡尔曼滤波，第三是将二者的信息进行融合。

Result The three strains all produced the AHL signal molecules; the strains FML05-land FML05-2 produced two types of AHLs at least and the N-3-oxo-octanoyl-homoserine lactone was the predominant signal molecules. The production of siderophore and proteinase in FML05-2 were reduced by co-incubation with AHL degrader strain.

结果］3株菌均产生AHLs信号分子；菌株FML05-1、FML05-2至少产生两种AHLs分子，二者所产生的主要信号分子是N-3-氧代－辛酰基－高丝氨酸内酯(N-3-oxo-C8-HSL)；FML05-2与降解AHLs的菌株共同培养，发现嗜铁素的产量与蛋白酶活性明显下降。

The detecter signal transmits in analogous mode.All the NIM modules for data acquisition are fixed in a shock proof bin. Data processing is accomplished by IBM PC/XT computer. The main performance :Signal transmission rate and the difference of C/O ratio in oil and in water are better than the same product made in foreign country.

探头信号采用模拟传输方式，获取部分的NIM插件全部固定在防震机箱上，数据处理选用了IBM PC/XT微机，其中主要技术指标、信号传输率和油水碳氧比差值均优于美国Schlumberger公司的同类产品。

Thus, the signal information is treated as virtually encoded data for the channel of interest, and may comprise essentially any type of signal that is known or determinable, such as a pilot, synchronization, traffic, or control channel.

因此，将信号信息作为针对感兴趣信道的虚拟编码的数据进行处理，可包括基本上任何类型的已知的或可确定的信号、如导频、同步、业务或控制信道。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
