Feedback shift register sequences versus uniformly distributed random sequences for correlation chromatography.
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.
