模式噪声 meaning in Chinese

modal noise

The column output circuit is realized by double sample and hold circuit which can effectively decrease fpn ( fixed pattern noise )
列输出电路采用双采样电路,该电路能有效地消除固定模式噪声。
Every column in sensor array work in parallel and have their own cds noise reducing circuit . the signals after fpn reducing are output from the output buffer amplifiers
传感阵列中各列感光单元的传感信号并行输出，分别由对应的相关二次采样电路进行降噪处理，去除固定模式噪声后的信号通过输出缓冲放大电路进行输出。
The correlated double sampling ( cds ) circuits structure is used to reduce the fixed pattern noise ( fpn ) of the cmos sensors , and improve the signal - noise ratio ( snr ) . the 256 photodiodes arrayed 4 quadrants sensor consists 16x16 active photodiodes array . correlated double sampling processing circuits , output buffer amplifiers and digital control part
针对cmos制造工艺中mos器件固定模式噪声( fixedpatternnoise ， fpn )较大的不足，研究中采用了相关二次采样( correlateddoublesampling ， cds )电路降低固定模式噪声，从而提高了传感器的信噪比( signalnoiseratio ， snr ) 。
