Abstract
A digitally-tunable filter includes a tunable filter circuit () for generating an output signal by processing an input signal based at least on a plurality of filter control signals (). The filter also includes an input power sampler () for sampling an input power of the input signal, an output power sampler () for sampling an output power of the output signal, and a tuning processor () for generating the plurality of filter control signals based on at least one channel control signal () associated with a current communications channel and a comparison of the input and the output powers. In the filter, the plurality of control signals configure the tunable filter circuit to attenuate at least a portion of the input signal if a difference between the input power and the output power is less than a threshold value.
