Properties and computation of Born--Jordan related time-frequency distributions

We study properties of functions and tempered distributions
by means of certain Cohen class bilinear time-frequency distributions
related to the Born--Jordan quantization of pseudo-differential operators.
We obtain smoothness and continuity results for the involved transforms,
and also present an efficient FFT-based algorithm,
computing time-frequency pictures of real-life signals.
Advantages of this approach are demonstrated by comparisons to spectrograms.
