二次采样 meaning in English
sub-samples
Examples
- 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。 - Digital feedback twice sampling a / d converter is based on common accurate dual integral a / d converter . during the second sampling , through the control logic , programmable counters and switch control , realize digital feedback and substitute primary analogue feedback realized by high accuracy d / a converter
在第二次采样中，通过控制逻辑、可编程计数器和开关控制来实现数字反馈，以取代原有的两次采样a / d转换器中通过高准确度d / a转换器所实现的模拟反馈。 - Third , mensurated the front axle ' s load - time history when truck was running on general tar - paved roads , mountainous roads and the proving ground enhancement roads , second sampled and pretreated to the load - time history with rpc software of mts corporation , acquired the relationship of the frequence of the mean and amplitude load , obtained the zero mean equivalent loads using goodman experiential fatigue equation , acquired the weibull distributing functions of equivalent loads of respective roads
第三，测定了汽车前桥在一般沥青公路、山区公路和试验场强化试验路面的载荷时间历程。对载荷时间历程进行了二次采样和数据预处理。采用雨流计数法得到了各路面的载荷均、幅值的频次关系，并根据goodman经验疲劳公式，得到了零均值的等效载荷及相应的频次。 - 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 ) 。
