in the Time-Frequency plane) of a signal that consists of:

(1) **two slighly different Gabor atoms** whose internal frequencies

progressively increase, .

(2) A **dirac**,

(3) A **sinusoid**,

(4) A **noise** that increases for each repeated sequence. (23')

In the Time-Frequency plane: [0,1] vs.[0,1/2].

Observe the calculation interference terms.
