Accompanying code for the paper "Alias-free simulation of static diode circuits using the Lambert-W function" by F. Esqueda and V. Välimäki. Submitted to IET Electronics Letters, October 2017.

The attached MATLAB script implements a diode clipper model using the first- and second-order antiderivative antialiasing methods and generates the spectrogram shown in Fig. 2.

The antiderivative methods are implemented as described in:
