They are manifest in a TFD of multicomponent signals as spurious artifacts arising from interactions between the various signal components, and they can often appear at times and/or frequencies inconsistent with the underlying physical nature of the signal, causing misinterpretation [2], [3], [4]. There are many time frequency distributions that avoid the cross term effect; the best are the Choi-Williams ED (Exponential Distribution) [1] and Levin's IPS (Instantaneous Power Spectrum) [9]. In this paper we combine the cross term reducing philosophy of the ED and IPS to obtain a new TFD that most effectively reduces the cross term effect. Surprisingly, the new TFD also satisfies most desired TFD properties. © 1995 Birkhäuser.Attenuation; Frequencies; Frequency domain analysis; Signal interference; Signal processing; Signal theory; Time domain analysis; Exponential distribution; Instantaneous power spectrum; Interference attenuation; Interference concentration; Time frequency distribution; Circuit theoryjournal article10.1007/BF012603362-s2.0-0029215408
