Apparatus for regenerating signals within a frequency band

Apparatus for regenerating signals within an input frequency band, comprising:

• a spectrum analyzer circuit repetitively triggerable to transform on each such triggering a set of signals mutually displaced in frequency within a predetermined frequency band to a corresponding series of signals mutually displaced in time according to a predetermined frequency-to-time relationship;
• a synthesizer circuit for transforming a received series of time displaced signals from said analyzer circuit into a set of frequency signals in accord with a predetermined time-to-frequency relationship that so matches the frequency-to-time relationship of said analyzer circuit that the same frequency differences exist between a set of signals from the synthesizer circuit as existed between the set of signals that gave rise thereto in the input frequency band of the analyzer circuit;
• timing means coupled to said analyzer circuit and said signal regenerator circuit to supply thereto signals for triggering said analyzer circuit and providing a time reference for said signal regenerator circuit;
• and
• signal processor means coupling said synthesizer circuit to said analyzer circuit and coupled to said timing means to receive time reference signals therefrom to selectively inhibit the transmission to said synthesizer circuit of time-displaced signals occurring at one or more selected times in a series.
