Abstract
A filter system capable of automatically adjusting bandwidth includes a filter and an adaptive unit. The filter is used for filtering a digital signal to generate an output signal to an application unit. The adaptive unit is used for generating an adjustment signal to the filter according to the digital signal and the output signal. The filter dynamically adjusts bandwidth of the filter according to the adjustment signal.
