    If you konw the voltage and current as a function of time of a spark acorss a sparkgap, can you calculate the frequencies? If so, how?

    Convert the time domain waveform into a frequency domain spectra versus time. The spark is confined to a short time, so the frequency components will grow and fade in the same amount of time.
