“…Most of the applications of the RS polynomials have been mainly in antenna design for communication systems, 15 in signal processing, 16 and in information theory, 17 while more work has been done on their mathematical characteristics 18 and geometrical features. 19 To the best of our knowledge no attempt to use their wide-band frequency spectra property has been reported in electrochemical impedance spectroscopy measurements.…”

Electrochemical impedance spectroscopy (EIS) is an increasingly important diagnostic tool in many industries. An obstacle that arises when employing EIS in low, sub-Hz frequencies is the long measurement time associated with using the conventional frequency-sweep method. One possible solution to this problem is to use wide-band signals that cover at once the entire frequency range of interest. Here, we explore and validate the use of a signal obtained from the Rudin-Shapiro polynomial over the frequency range 10 mHz-10 Hz. The signal was tested on an RC circuit and the results were compared to the classical method for verification.
