ABSTRACT:
Phase shifted frequency components of wide bandwidth, composite signals are ocused for analysis with high resolution by circuitry which includes both a Chirp-Z and a superheterodyne signal analyzer. An interface between the analyzers synchronizes the outputs therefrom relative to each phase shifted frequency component. Preferred embodiments are disclosed with the analyzers generally arranged in either parallel or series and replicating circuitry may be included in the latter to sustain the integrity of the phase shifted frequency components for some predetermined period of time.
