Provided is a digital output overflow processing device comprising: an excessive output detecting unit which detects an overflow in a digital signal outputted from a digital signal processor, wherein the digital signal processor is a digital constituent part which performs a digital signal processing required for a relay signal in a digital part mounted in a relay device for relaying a mobile communication signal; and a digital gain control unit which is arranged on a signal transfer path of the digital signal, and controls a gain based on at least one among whether an output is excessive, which is delivered as a detection result from the excessive output detecting unit, and an excessive output level such that a level of an excessively-outputted digital signal is changed to be not higher than a preset tolerance level. According to the present invention, a digital output overflow and digital spurious problems can be solved by monitoring whether an output signal outputted from a digital signal processor is excessive. |
