ABSTRACT:
The invention improves the control behavior of a control circuit for digital signals which is used in AGCs (automatic gain control), using a simple supplementary circuit. In a first example of an embodiment, the output signal of an integrator member is looped back to the input of said integrator member in the loop-back branch of the control circuit. In a second example, a counter is provided. Said counter monitors the overflow of the integrator member and weights the input signal accordingly.
