Abstract
Method for capturing a high dynamic range signal includes: receiving the wideband analog signal; digitizing the wideband signal by a wideband ADC; detecting N strongest sub-bands in the digitized wideband analog signal; adaptively programming N bandstop filters to block the detected N strongest sub-bands from being digitized by the wideband ADC; adjusting a gain of output signals of the N bandstop filters to amplify said output signals; digitizing the amplified output signals by the wideband ADC to obtain a first digitized signal; adaptively programming N passband filters to pass the detected N strongest sub-bands to N ADCs, respectively; digitizing the detected strongest N sub-band signals output from the N pass-band filters by the respective N ADCs to obtain a plurality of second digitized signals; and processing the first digitized signal and the plurality of second digitized signals to identify any duplicate bands.
