Abstract
The present invention relates to a device for detecting the locking of an automatic gain control circuit, the automatic gain control circuit receiving a signal to be regulated, a check signal and a sampling control signal for driving the operation of the circuit. The detection device includes a comparator receiving the check signal and the signal to be regulated or a signal representative of the signal to be regulated. The comparator generates two logic signals, the states of which form a specific combination of logic states when the value of the signal to be regulated is in a range of values including the value of the check signal. A logic comparator circuit generates a logic comparison signal, the state of which is representative of the presence or absence of this specific combination, and a storage means, driven by the sampling control signal, stores the state of the signal provided by the logic circuit.
