amplification system of a radio signal from television signal decoder comprising such a system

The invention relates to a wireless signal amplification system (1) comprising amplification means (6) consisting of numerous different amplifiers (61 to 6n) which are distributed in an analogue processing chain (4). Said invention also comprises means for converting (12) analogue signals into digital signals which, at input, are connected to the outlet of said analogue processing chain (4) and, at output, are connected to at least the gain control means (16) of said amplification means (6) according to a value that is representative of a characteristic of said wireless signal (1). In this way, the sampling of said wireless signal (1) by the converter (12) is optimised. Said control means (16) comprise means for establishing an average gain control signal (18). The inventive system is characterised in that said control means (16) also comprise, for each of said amplifiers (61 to 6n), means for calculating an individual gain control signal (20i to 20n) according to a transfer function (H1 to Hn) which is specific to each amplifier and which is applied to the average gain control signal.
