WebAug 1, 2011 · 1. Measured the magnitudes of all the harmonic peaks (in dB) in the FFT plot above (listed below). 2. Normalized them to the fundamental by subtracting the magnitude of the fundamental from each. 3. Plugged the numbers into Fred's spreadsheet. (2nd attached spreadsheet is the one with the results.) WebJun 11, 2024 · Is there a way of obtaining an average value of a measurement over time in LTSpice? For instance, I've just measured the power dissipated by a resistor in a sim, and although the graphic is very telling, it's also full of "spikes" that are very hard to read just by looking at them. Even though the spikes can reach levels of up to 400W, I know ...
