WebJul 21, 2024 · The .FOUR command has existed in SPICE for almost as long as SPICE itself existed. .FOUR computes the RMS amplitudes of the harmonic components, which makes sense in that context. FFT can be considered an extension of the .FOUR command. Since its use is similar to .FOUR, it also computes and displays RMS amplitudes. Andy WebDec 7, 2024 · The RMS function in LTSpice is a standatd function which solves the attached integral. This works well for a voltage or a current over time. In your RMS(v(OUT)*i(RL)) script LTSpice you force LTSpice to apply the same integral to the product of voltage times current over time and this is undefined or just meaningless. twixs tests on animals
