The article explains the noise component in a signal-to-noise ratio (SNR), which represents the connection between signal and noise power and the root-mean-squares (rms) of signal and noise voltages. E...
最后,SINAD(信号与噪声+失真比)定义为信号基波输入的RMS值与在半采样频率之下其它谐波成分RMS值之和的比值,但不包括直流信号。对SAR和流水线型而言,SINAD的理论最小值等于理想的信噪比,或6.02N+1.76dB。至于Δ-Σ转换器的理想SINAD等于(6.02N+1.76dB+ ,其中fS是转换器采样频率,BW是感兴趣的最大带宽。非理想SINAD...

The ratio of the amplitude of a desired signal at any point to the amplitude of noise signals at that same point; often expressed in decibels; the peak value is usually used for pulse noise, while the root-mean-square (rms) value is used for random noise. Abbreviated S/N; SNR. McGraw...

An example is introduced where the RMS phase error is calculated for representative sea ice targets using specifications from an operational synthetic aperture radar. The analytic solution for the phase probability density function given a known, and constant S/N is presented. An approximation to the...
SNR(Signal to Noise Ratio,信噪比): 指在规定输入电压下的输出信号电压与输入电压切断时,输出所残留之杂音电压之比,也可看成是最大不失真声音信号强度与同时发出的噪音强度之间的比率,通常以S/N表示。一般用分贝(dB)为单位,信噪比越高表示音频产品越好,常见产品都选择60dB以上。
Signal-to-noise ratio (SNR) is the most important parameter characterizing the performance of a CCD camera. It is defined as the ratio of peak-to-peak amplitude of the composite video signal to the root-mean-square (RMS) noise amplitude. The higher the SNR is, the better the picture qual...
