US 2008/0291983 A1 · SIGNAL ADJUSTMENT DEVICE

Abstract

A signal processor and method for receiving a digital signal and providing an output signal to a signal receiving device includes a receiver for receiving a digital signal from an antenna and a control circuit for adjusting signal attenuation of the digital signal and generating an output signal. The control circuit includes a variable signal attenuator. The control circuit is operable to sample the output signal and to adjust the variable signal attenuator to adjust signal attenuation and the output signal toward a target output level. The adjusted output signal is communicated to the signal receiving device. The signal processor may include a splitter that receives the output signal of the variable signal attenuator and provides two output signals, one of the output signals being communicated to the signal receiving device and another of the output signals being sampled by the control circuit.
