SUMMARY
To derive an equation from a set of data obtained from Fourier output, cubic splines are a recommended method, especially when the data exhibits smooth characteristics. Curve fitting is not advisable in this scenario due to the uncertainty of the underlying function type. The discussion highlights the effectiveness of cubic splines as a solution for interpolating data points without prior knowledge of the function form.
