$D$-optimal saturated designs: a simulation study

, 2014
In this work we focus on saturated $D$-optimal designs. Using recent results, we identify $D$-optimal designs with the solutions of an optimization problem with linear constraints.

Efficiency of low power audio amplifiers and loudspeakers [PDF]

, 2001
In this paper we look at the load presented to audio amplifiers by real transducers. We consider the power losses in Class-AB and Class-D amplifier topologies, and determine that in order to predict efficiency it is necessary to consider the amplifier ...
