  • SIGNAL PROCESSING APPARATUS AND SIGNAL PROCESSING METHOD
    Publication number: 20210083698
    Abstract: Example signal processing apparatus and signal processing methods are described. One example signal processing apparatus includes a signal matching circuit, a first signal processing branch, and a second signal processing branch. An output end of the signal matching circuit is separately coupled to an input end of the first signal processing branch and an input end of the second signal processing branch, and an output end of the first signal processing branch is coupled to the input end of the second signal processing branch.

  • Local oscillator feedthrough signal correction apparatus and method, and microprocessor control unit
    Patent number: 10615827
    Abstract: The present disclosure discloses a local oscillator feedthrough signal correction apparatus, including a microprocessor control unit, a first digital-to-analog converter, a second digital-to-analog converter, a mixer, a local oscillator, a signal output line, a signal splitter, and a detector tube. The signal splitter is disposed in the signal output line, and the first digital-to-analog converter and the second digital-to-analog converter are configured to provide the mixer with quadrature direct current components VI and VQ used for local oscillator feedthrough signal correction. The mixer outputs a local oscillator feedthrough signal to the signal output line. The signal splitter obtains the local oscillator feedthrough signal by means of splitting, and the detector tube detects the local oscillator feedthrough signal.
