Title:
SIGNAL REMOVAL FOR CHECKING SPECTRUM OF OTHER SIGNAL
Document Type and Number:
Japanese Patent JP2018067913
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for checking the spectrum of at least another RF signal, by removing the extracted radio frequency (RF) signal.SOLUTION: In a system 100, a mixed signal is digitized by an ADC and the same signals, i.e., a first digital signal 116 and a second digital signal 120, are generated. An extraction signal 122 is extracted by delaying the first digital signal by a prescribed delay time in a delay circuit 114, and processing the second digital signal in a neuromorphic signal processor 118. The prescribed delay time corresponds to delay embedding by the neuromorphic signal processor 118. A signal phase and amplitude adjustment module 126 adjusts phase lag and amplitude of the extraction signal based on the phase lag and amplitude of the first digital signal. An input signal 134 for check is supplied by cancelling the adjusted extraction signal from the first digital signal.SELECTED DRAWING: Figure 1
