Hi,

I'm performing a noise analysis in LTspice IV. Unfortunatly te function LTspice2Matlab, which is available at www.mathworks.com just supports transient and AC analysis. So I have to export my resulting noise density voltage via File -> Export. The exported file format is a txt document. After importing the values from this txt-file to MATLAB, my post processed results e.g. noise RMS or mean value of the noise density differ from the values evaluated directly in LTspice.

Is there a possibility to increase the decimals of the export file?

Hi,

I solved the problem. The mismatch between MATLAB and LTspice was a result of the non-equidistant frequency steps. By using the MATLAB function trapz the results match. So no need to worry about the export decimals.
