  The Intensity Impulse Response Function of an optical system apodized with parabolic amplitude filters of the first order has been studied. The results obtained have been discussed with the help of tables and figures. It is observed that the locations of the first minimum and the secondary maxima of the point spread function do not depend on the value of the apodization parameter. These depend only on the values of the bias or D.C value of the Pupil Function.

Key-words:  Apodization, Parabolic filters, Impulse Response Function etc.
