ABSTRACT:
A method and apparatus for performing simultaneous instantaneous signal frequency measurement using a signal sorter in conjunction with a frequency measurement receiver. Simultaneous signals of similar amplitude are received and successively applied to a plurality of either frequency or time dependent signal modifying circuits, via switching circuitry. Respective ones of the received signals are separated with respect to frequency in one or both of amplitude and time from one another via the signal modifying circuits which can be, for instance low pass and high pass filters, or positive and negative dispersive delay lines. In addition, the received signals are applied to a straight-through signal path for transmitting the signals to the frequency measurement receiver unaltered. Signals output from the signal modifying circuits and the straight-through signal path are successively applied to the frequency measurement receiver for detecting the frequency of respective ones of the separated received signals.
