A stage converter of electric signals comprises a circuit (1) with variable gain factor, the controlling inputs of which are connected to the outputs of a generator (3) of controlling signals to ensure variation of the gain factor of the circuit (1) in accordance with a preset stage function of time, and a negative feedback circuit connected between the input and output of the circuit (1) and containing a second circuit (2) with variable gain factor, the controlling inputs of which are connected to the outputs of the generator (3) to ensure variation of gain factor of the second circuit (2) in inverse proportion to said stage function of time. |
