Unfortunately, traditional WDF techniques falter at t he complexity of typical audio circuits, which contain complicated (non-series/parallel) topologies and multiple nonlinear devices (e.g., diodes, transi Kurtjameswernerdissertation-Augmented.pdfstors, triodes). In this dissertation, 1 review classical WDF techniques and propose novel ways of systematically modeling circuits with complicated t

I explain their substantial limitations in the context of modeling analog audio circuitry. To overcome these limitations, I introduce a novel Modified-Nodal-Analysis-based a Kurtjameswernerdissertation-Augmented.pdfpproach to creating WDFs from circuits with complicated (non-series/parallel) topologies ami show it in action on several versions of t he Bass Drum's
