Abstract
1. In a frequency measuring system for measuring and indicating the frequency position of a signal within an extended band of frequencies, wherein said extended band of signals is divisible into a plurality of first sub-bands of equal extent and a plurality of second sub-bands of equal extent, the frequency extents of said first and second sub-bands being respectively different from each other, means for converting said signal to first signals only one of which occurs within each of said first sub-bands, means for further converting said signal to second signals only one of which occurs within each of said second sub-bands, means capable of measuring plural frequency locations within said plurality of first sub-bands for indicating the frequency location within said first sub-band of said first signal, and means capable of measuring plural frequency locations within said plurality of second sub-bands for indicating the frequency location within said second sub-band of said second signal.
