Set the degree of the polynomial for the interpolation function. This parameter is used in functions INTERPOLATE(V) and FOUR(V,F). The default value is 1.

The algorithm used to perform the Fourier transform requires that the time interval between the samples must be equally spaced. As a consequence, the vectors for which the spectral components are to be calculated are interpolated on a scale corresponding to a period of the fundamental frequency. The interpolation function is regulated by the options: Polynomial grade for the interpolation function and Number of interpolated points for Fourier analysis.

Set the degree of the polynomial for the derivation function. This parameter is used in function DERIV(V). The default value is 2.

Set the number of samples to be generated to perform Fourier analysis. This parameter is used in function FOUR(V,F). The default value is 1024.

Set the number of harmonics to be calculated. This parameter is used in functions FOUR(V,F) and FREQ(V). The default value is 10.

Set the number of decimal places for Fourier analysis results. The default value is 6.
