摘要: Apparatus for eliminating spurious spectral components from a analyzer output signal. An input signal is mixed with two separate local oscillator frequencies separated by frequency offset value to produce intermediate-frequency signals, which are processed in analyzers. The outputs of the analyzers then compared identify and eliminate any that do not differ value.
