... We will remind one of these properties in the following, without proof. P3. With the aid of a frequency tracking filter, the ridge of a continuous wavelet transform of the input signal can be computed. Analogous properties of the argument of the same time- frequency response can also be defined. IV. IMPLEMENTATION ...
