Random amplitude and phase errors in seismic input data introduce a coherent distribution of migration half‐circles or “smiles”, the occurrence of which may cause a significant decrease of signal‐to‐noise ratio. In addition, the effect of quantization errors is discussed for different wordlengths, used both during acquisition and during data processing. Results of sign‐bit recordings are shown.
