The wave digital filter (WDF) technique derives digital filters from analog prototypes that
classically have been restricted to passive circuits with series/parallel topologies. Since most …

We present a novel framework for developing Wave Digital Filter (WDF) models from
reference circuits with multiple/multiport nonlinearities. Collecting all nonlinearities into a …

There is a growing interest in Virtual Analog modeling algorithms for musical audio
processing designed in the Wave Digital (WD) domain. Such algorithms typically employ a …

We derive a novel explicit wave-domain model for “diode clipper" circuits with an arbitrary
number of diodes in each orientation, applicable, eg, to wave digital filter emulation of guitar …

A large class of transcendental equations involving exponentials can be made explicit using
the Lambert W function. In the last fifteen years, this powerful mathematical tool has been …

A dependable circuit simulation plays an elementary part in the process of commercial
circuit design. However, when Alfred Fettweis invented the concept of Wave Digital Filters …

Abstract We present a Modified-Nodal-Analysis-derived method for developing Wave Digital
Filter (WDF) adaptors corresponding to complicated (non-series/parallel) topologies that …

Aliasing is a commonly encountered problem in audio signal processing, particularly when
memoryless nonlinearities are simulated in discrete time. A conventional remedy is to …

In this paper, iterative zero-finding techniques are proposed to resolve groups of
nonlinearities occurring in Wave Digital Filters. Two variants of Newton's method are …

ABSTRACT The Fender Bassman model 5F6-A was released in 1958 and has become one
of the most revered guitar amplifiers of all time. It is the progenitor of a long line of related …
