Abstract
A system for filtering a signal includes a plurality of filter modules coupled in series. Each filter module includes a filter and a variable gain element. Each filter is capable of. receiving an input signal, attenuating a portion of the input signal that is outside a passband associated with the filter, and outputting at least a portion of the input signal that is within the passband associated with the filter. Each variable gain element is capable of receiving a control signal and inducing a gain in an output of the filter based on the control signal.
