ABSTRACT:
A filter is delineated that may have an input for receiving an input signal including a plurality of different frequencies and an output for passing an output signal within a first frequency band. The filter may include a circuit coupled between the input of the filter and the output of the filter such that the circuit may add one or more zeros within a second frequency band to increase attenuation of the input signal within the second frequency band. Portions of the filter may be employed to form such a circuit. The filter may be used by an electrical system employing the filter.
