1. A computer-implemented method of extending harmonics of a band-limited harmonic signal through the use of a processor, the method comprising:

  • transforming, through the use of a processor, a band-limited harmonic signal from a time domain to a frequency domain to obtain a complex spectrum of the band-limited harmonic signal;

    performing, through the use of the processor, a non-linear transformation on the complex spectrum of the band-limited harmonic signal in the frequency domain which extends harmonic content of the band-limited harmonic signal to frequencies above an upper frequency limit of the band-limited harmonics signal, where the non-linear transformation comprises performing a linear convolution; and

    inverse transforming, through the use of the processor, the extended complex spectrum of the band-limited harmonic signal back into the time domain.
