The process for the analysing frequency spectrum of the information component (G0) of the video signal having certain dimensions in (N+1) frequency bands where n is a constant over 2 includes a pipe line having a set of sequentially arranged sampled-signal converters (100- 1,...100-N) for analysing the frequency spectrum during delayed real time. The converters have the first input terminals (G0,..., Gn), the second input terminals (CL1,..., CLn), the first output terminals (G1,...,Gn), and the second output terminals (L0,...,Ln-1). The second input terminal of each converter receives divided sampling frequency clock (CL1, ...,CLn). |
