Abstract :
Recently, numerous strategies have been proposed for computing discrete time-frequency distributions such as the Wigner distribution. The author describes an efficient and straightforward strategy for computing time-frequency distributions that are members of Cohen´s class. The strategy is based on the work by A.H. Nuttall (Naval Underwater Syst. Center, Tech. Rep., 8533, April 1989) which has resolved the questions concerning aliasing and required sampling rate for the Wigner distribution
