ABSTRACT:
The invention is a signal processing system and method having increased bandwidth. An embodiment of the invention is a method of processing an analog input signal. The analog input signal is split into a first set of signals. The first set of signals are filtered. The first set of signals are digitized to form a second set of signals. The second set of signals are filtered to form a third set of signals. The third set of signals are combined to form a combined signal by adding the signals in the third set signals together to form a digital version of the analog input signal.
