Takes a signal in and performs a full harmonic analysis, including measuring the fundamental frequency tone and harmonics, and returning the fundamental frequency, all harmonic amplitude levels, and the total harmonic distortion (THD). Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance.
