Fourier Analysis using LTspice & Excel
Frequency & time domain analysis made easy
LTspice is a circuit analysis program with many powerful functions, including a spectral analysis tool. It is freely downloadable and has an active user group. Together with Microsoft’s well-known Excel tool and three free spreadsheets from this web page, Fourier analysis can be performed on many common waveforms found in electronics.
