Abstract
An apparatus comprising a first filter, a second filter, a third filter, and a fourth filter. The first filter may comprise a low pass filter having a first bandwidth and configured to present a first output signal in response to an input signal received at an input port of the apparatus. The second filter may comprise a high pass filter having a second bandwidth and configured to present a second output signal in response to the input signal received at the input port of the apparatus. The third filter may comprise a low pass filter having a third bandwidth and configured to present a third output signal in response to the second output signal. The fourth filter may comprise a high pass filter having a fourth bandwidth and configured to present a fourth output signal in response to the second output signal.
