According to the device and method for the automatic gain control, the present invention controls the received signal intensity to a constant level by the receiver which is used to receive the exerted digital broadcast signal. With this end in view, it compensates the incoming signal received by the gain error detector by the compensating signal, detects the gain error, accumulate the gain error detected by the loop filter, and the compensating signal generator compensates the accumulated gain error by the prescheduled penalty function to generate the compensating signal, and compensates the received incoming signal detected by the gain error detector according to the generated compensating signal. |
