**Appendix A**

Table A1 shows the maximum error *ε*max obtained with the proposed WPD method in each of the 13 tests described in Sections 4.2 and 4.3, reporting the harmonic order that registered the maximum error. For each test type (modulation), the maximum error obtained among all waveforms is identified in bold. The maximum error overall is marked with a star (∗).


**Table A1.** Maximum errors obtained for each validation assay.
