Signal removal to examine a spectrum of another signal

A system for removing an extracted radio frequency (RF) signal to examine a spectrum of at least one other RF signal, comprising:

• an analog-to-digital converter (ADC) for receiving a mixture signal, the mixture signal comprising a plurality of separate source signals from different signal sources, the ADC digitizes the mixture signal and generates a first digitized signal and a second digitized signal, wherein the first digitized signal is the same as the second digitized signal;
• a delay circuit for delaying the first digitized signal by a predetermined time delay;
• a neuromorphic signal processor for processing the second digitized signal to extract an extracted signal from the second digitized signal, wherein the predetermined time delay corresponds to a delay embedding in the neuromorphic signal processor;
• a signal phase and amplitude adjustment module that adjusts the extracted signal based on a phase delay and amplitude of the first digitized signal;
• and
• a summing junction for cancelling an adjusted extracted signal from the first digitized signal to provide an input examination signal.

A computer program product for removing an extracted radio frequency (RF) signal to examine a spectrum of at least one other RF signal, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory medium per se, the program instructions being executable by a device to cause the device to perform a method comprising:

• receiving a mixture signal by an analog-to-digital converter (ADC), the mixture signal comprising a plurality of separate source signals from different signal sources;
• digitizing the mixture signal by the ADC and generating a first digitized signal and a second digitized signal, wherein the first digitized signal is the same as the second digitized signal;
• delaying the first digitized signal by a predetermined time delay;
• processing the second digitized signal in a neuromorphic signal processor to extract an extracted signal from the second digitized signal, wherein the predetermined time delay corresponds to a delay embedding in the neuromorphic signal processor;
• adjusting a phase delay and amplitude of the extracted signal based on a phase delay and amplitude of the first digitized signal;
• and
• cancelling an adjusted extracted signal from the first digitized signal to provide an input examination signal.
