信号畸变 meaning in English
signal distortion
Examples
- In data communications , a deterioration in the characteristics of a signal for whatever reason
在数据通信中由于某种原因而造成的字符信号畸变现象。 - In data communications , a deterioration in the characteristics of a signal for whatever reason
在数据通信中由于某种原因而造成的字符信号畸变现象。 - To solve the aberrance problem of electromagnetic signals caused by fourier transform of limited time and discrete sampling , the function and the influence of windows with different scales were discussed
摘要针对电磁法物探观测信号离散傅立叶变换中信号畸变问题，研究了不同尺度窗口对信号分析的作用和影响。 - When signals pass high power amplifier , they would be distorted in amplitude and phase , leading to spectrum spread and distortion of in - band signals , both of which would weaken performance of the whole system in turn
在无线通信中,信号在通过高功率放大器时会产生幅度和相位失真,造成频谱扩展以及带内信号畸变,导致整个系统性能的降低。 - As to the video signal , alarm signal , control signal , are all weak electricity signal , exceedingly easily be subjected to the jam , in case the power supply system does not steady , wave propag ation is greatly , the harmonic content of power source overtops , the veins wave factors are great unduly , and even power source equipment breakdown , outputting abnormal , will be about to affect the video signal image effect , and dependability cuts downs to the security and alarming system . we adopt fast fu lye ' s mutation rule - fft alternatives , by the way of carrying fft alternatives to the local junction circuit , regulated power supply , ups ' s power source , and switch power source , thereby diagnose every degree harmonious wave content of power souse , and abnormal coefficient , compared to the normal working situation . thereby diagnose out the working condition of the regulated power supply , ups ' s power source , and switch power source
如果有供电系统不稳定、波动大，电源的谐波含量过高，纹波系数过大，乃至电源设备损坏、输出异常等情况出现，将会严重影响视频信号的图像效果，大大降低防盗系统的稳定性和可靠性，我们采用快速傅利叶变换原理，即fft变换，通过对市电、稳压电源、 ups电源、开关电源等的电压信号进行fft变换，从而得出信号中各次谐波的含量及信号畸变系数，并将其与正常工况下的参数进行对比，从而进一步诊断出稳压电源、 ups电源、开关电源等设备的运行状况；组成监控系统的设备长期处于工作状态，往往由于设备散热条件不好、设备老化故障等原因导致设备表面温度过高，从而影响设备的正常运行，降低设备的使用寿命。
