User’s Manual Vol. 1 More About Noise Elimination For each trace, the following computation is performed: n E (i , p) = ∑ [ A( k )] 2 n k =1 1 A ( k ) Q ---------------E ( i, p ) • Processing After correlation assuming m is the last stacking fold before writing to tape, the following computation is performed: C (i ) = 1 m ∑ p =1 1 E (i , p) Finally, for each trace i, each sample is multiplied by C(i).
