signal-noise rate的意思|示意

Signal sampling system of video communication over network usually has a low sampling rate suffering from the limited bandwidth, so aliasing noise is big problem.

受传输带宽限制，网络视频采集系统的采样率低，欠采样噪声严重。

The results show that while introducing smart antenna technology in wireless telemetry systems, it can efficiently raise signal-to-noise ratio and improve bit error rate performance of the system.

结果表明，在无线遥测系统中采用智能天线技术，能够有效地提高系统的信噪比，改善系统的误码性能。

Therefore, using this technique in active image sequence, the satisfied results of suppressing noise and improving signal-to-noise rate can be obtained and the blur degree of moving...

对于活动红外图像序列，该技术能够有效地抑制噪声、提高信噪比，也能够降低运动目标的模糊程度。

In the same transmission system, in order to get the same error rate, the coding rate is higher the needed rate of signal to noise is higher.

并且在同一个传输系统中为了得到相同的误码率，码率越高则需要的信噪比就越大。

On the same time, we employ digital correlation technique to improve signal-to-noise rate, and get satisfied results.

同时采用数字相关技术提高信噪比，得到了较满意的结果。

With the method of over sampling and averaging, the resolution and signal noise rate(SNR)can be raised without extra ADC.

但采用过采样求均值的方法，既可以不采用片外ADC，又能提高ADC测量的分辨率和信噪比，很好地控制了产品成本，又提高了产品的性能。
