Narrowband multifrequency binary measurement using phase shift keyed modulation

Multifrequency binary testing (MBT) employs binary test signals to evaluate frequency response estimates. Multifrequency binary sequence (MBS) test signals allow the capture of a wide variety of frequency information with excellent signal-to-noise-power ratios for their dominant harmonics. Two identification channel coding theorems use compact binary codes and digital modulation as the basis of signal engineering techniques to design MBS test signals. Information theory is used to design a novel MBS in symbol form which will allow simple microcomputer generation of these signals. Phase-shift-keyed (PSK) MBS signals are designed with a zoom attribute to identify narrowband frequency information with a high spectral resolution. The frequency zoom attribute is similar to the optical zoom of a camera and is designed to detail a narrower and narrower portion of a frequency response record
