1. A wide dynamic range automatic gain control device comprising a variable gain amplifier, a means with a signal strength indicator measuring the logarithmic value of the amplifier output signal, and an integrating means providing a gain control signal of the amplifying means, characterized in that the variable-gain amplifier comprises a compensating means (110) receiving the control signal and generating a a response compensation signal for adjusting the gain of the amplifying means (18), with the input of the compensation means (110) connected to the output of the integrating means (22) and its output to the inputs for controlling the gain input amplifier (130) and the output amplifier means (170), the input signal (130) being fed to the second input of the input means (130) and its output connected to the input of the output means (170) through a filter means (160), the output of the output amplifying means (170) being connected to the corresponding measurement input means (20) which is of the type providing a linear measuring signal in accordance with the measured logarithmic power of the output signal from the amplifying means (18), the output of which is connected to the first input of the integrating means (22) integrating the difference between the measuring and a signal whose second input is a reference signal corresponding to g
