Real-time spectrum analysis of electrical signals and image transformation techniques and device for real-time signal processing in accordance with a hierarchical pyramid

摘要

A pipeline structure (Figure 3) is used for one or both of the following processes: (a) for the analysing, occurring at delayed real time, of the frequency spectrum of an information component (having one or more dimensions) of a given time signal (G0), the maximum frequency of interest of which is no greater than f0 and (b) for synthesising, in delayed real time, such a temporal signal (G0) from its frequency analysis spectrum (L0...G OMEGA ). Such a pipeline structure is particularly suitable for image processing of the two-dimensional space frequencies of television images which are defined by a temporal video signal (Figure 3). ……
