WebHarmonic analysis studies the properties of that duality and Fourier transform and attempts to extend those features to different settings, for instance, to the case of non-abelian Lie groups . For general non-abelian locally compact groups, harmonic analysis is closely related to the theory of unitary group representations. WebThe spectrum shows the different harmonic frequencies present in the waveform. It also measures inter harmonics. Thus, harmonic spectrum analyzer is very good tool for harmonic studies. For 50 Hz systems, 51 Hz, 93 Hz, 211 Hz etc are inter harmonics. Inter harmonic frequency is not integral multiples of fundamental frequency.
