Analytical estimation of the transverse emittance growth due to a point-like perturbation is performed for a proton synchrotron machine. This emittance growth is caused by the tune spread within the bunch. However, the emittance growth suffers a saturation effect caused by the same tune spread. Computer simulations on the emittance growth due to resistive wall instabilities and feedback systems verify qualitatively this emittance growth saturation effect. These simulations were accomplished in the Medium Energy Booster of the Superconducting Super Collider using the TADIMMI computer code
