  Removal of systematic effects is crucial in present and future CMB
experiments mapping large fraction of the sky. Accurate CMB measurements ask
for multi-feed array instruments observing the sky with a redundant scanning
strategy covering the same region of the sky on different time scales and with
different detectors for a better control of systematic effects. We investigate
here the capability to suppress 1/f noise features in Time Ordered Data (TOD)
by using the destriping technique described in Maino et al. (1999), under
realistic assumptions for crossing condition between different scan circles and
sky signal fluctuations on small angular scales. We consider as working case,
Planck-LFI simulated observations with few arminutes pixel size convolved with
LFI beam resolutions. We also extend the analysis to high values of the
knee-frequency and found a residual additional noise rms ~31% larger than the
pure white noise rms at fk=1 Hz which could be a critical issue in the
extraction of the CMB angular power spectrum. Furthermore we verified that
destriping quality does not significantly depend on the receiver sensitivity
whereas it improves proportionally to the improvement of sampling rate.
Therefore given a noise level, the higher the sampling rate, the better the
destriping quality.
