ABSTRACT:
An electronic device where the ratio between two amplification factors of two amplifiers, called main amplifiers, is adjusted using a control means. The control means constantly equalizes the output signals of the two main amplifiers by adapting one of the control signals. The output signals are acted on in order to adjust the control signals. Owing to the fact that the input signals are in a ratio N, this same ratio is obtained between the amplification factors of the two main amplifiers. The two main control signals, used to control the main amplifiers, are employed for controlling any other amplification factor of at least two other amplifiers or groups of amplifiers, so as to establish a ratio N between these other amplification factors. The main circuit thus allows N to be applied and regulated between the amplification factors of other amplifiers.
