Two alternative input sequences are commonly employed in correlation chromatography (CC). They are sequences derived according to the algorithm of the feedback shift register (i.e., pseudo random binary sequences (PRBS)) and sequences derived by using the uniform random binary sequences (URBS). These two sequences are compared. By applying the "cleaning" data processing technique to the correlograms that result from these sequences, we show that when the PRBS is used the S/N of the correlogram is much higher than the one resulting from using URBS.
在相关色谱法（CC）中通常采用两种替代输入序列。它们是根据反馈移位寄存器算法推导出来的序列（即伪随机二进制序列（PRBS））以及通过使用均匀随机二进制序列（URBS）推导出来的序列。对这两种序列进行比较。通过对由这些序列产生的相关图应用“清洗”数据处理技术，我们表明，当使用PRBS时，相关图的信噪比远高于使用URBS时产生的相关图。
