ABSTRACT:
This equalization arrangement has an input (1) for a signal to be equalized (A) and an output (30) for producing an equalized signal (B), which arrangement is formed, on one hand, by at least a correction element (5, 10) having an input for a signal to be corrected, an output for a corrected signal and a control terminal for receiving control information (10, 20) determining the correction to be made and, on the other hand, an equalization measuring circuit (22) intended to measure the equalization caused by the arrangement so as to produce said control information. An element is constituted on the basis of a hybrid circuit (50, 51) having accesses (A1) for the signal to be corrected and the corrected signal (A3) and auxiliary accesses (A2, A4) into which at least a reflecting circuit (54, 56-59) is inserted having a variable reflection as a function of said control information.
