Abstract :
A method for the calculation of the impulse response of quarter-plane and half-plane filters will be presented. The basic result is that the functions Hl (Z) defined by 
obey a simple difference equation. The necessary initial conditions can be obtained by restrictions on the support of the impulse response. The proposed method is of theoretical and practical interest. It provides a way for the calculation of the impulse response of half-plane filters having a total half plane as support.
