Narrowband multifrequency binary measurement using phase shift keyed symbols

摘要

Multifrequency binary testing (MBT), which uses multifrequency binary sequence (MBS) test signals, with high signal-to-noise power ratios for their dominant harmonics, to measure frequency response is considered. Information theory, in the form of descriptive languages and codes, digital modulation, and redundancy is used to design novel phase-shift-keyed (PSK) MBS symbols. A signal zooming operation, similar to optical zooming, is used to allow narrowband frequency response measurement with a high spectral resolution.
