Abstract :
The ideas behind different definitions of the discrete domain Wigner distribution (DDWD) are compared. It is shown that all the definitions are smoothed (filtered) versions of an elemental definition. An implementation of the DDWD as an add-on utility used in a digital spectrum analyzer is presented
