Abstract:
1. A signal treating apparatus for treating an input signal to present an output signal representing said input signal with improved signal accuracy over a predetermined signal range; the apparatus comprising: (a) an input signal receiving section coupled for receiving said input signal; said input signal receiving section presenting a first bandpass filtered representation of said input signal at a first circuit locus; said first bandpass filtered representation being limited to a first bandwidth; said input signal receiving section presenting a second bandpass filtered representation of said input signal at a second circuit locus; said second bandpass filtered representation being limited to a second bandwidth; (b) an amplifying unit coupled for receiving said first bandpass filtered representation and presenting an increased gain signal related with said first bandpass filtered representation at an amplifier output locus; (c) a detection portion coupled with said amplifier output locus; said detection portion presenting an indicator signal at a third circuit locus; said indicator signal being a third bandwidth representation of said increased gain signal; said indicator signal being limited to a third bandwidth less than said first bandwidth; and (d) a combining section coupled with said second circuit locus and said third circuit locus; said combining section presenting an output signal related with said second bandpass filtered representation of said input signal and said third bandpass filtered representation of said input signal; said input signal including an optical signal component and a radio frequency signal component.
