Half harmonics

WebMost electrical loads (except half-wave rectifiers) produce symmetrical current waveforms, which means that the positive half of the waveform looks like a mirror image of the negative half. This results in only odd harmonic values being present. Even harmonics will disrupt this half-wave symmetry. The presence of these even harmonics WebIn this video I show how to solve a quantum mechanics question on the half-harmonic oscillator, a variant of the simple harmonic oscillator. This solution involves the use of a …
