Influence of noise on peak integrals obtained by direct summation
The influence of zero-filling on the peak integral precision is examined when integration is carried out by direct summation of spectral point ordinates. A relationship that allows the computation of the standard deviation of the integrals is derived, taking into account the effects of apodization and noise intensity profile. Discrepancies between theory and experimentation arise from nonideal characteristics of noise. Copyright 1998 Academic Press.
