Harmonic Distortion Compensation in Voltage Transformers for Improved Power Quality Measurements
IEEE Transactions on Instrumentation and Measurement, 2019 Monitoring voltage harmonics represents one of the most important tasks in power quality assessment. In particular, the employed instrument transformer plays a key role in the achieved accuracy. Its harmonic measurement performance is typically evaluated

Two-Point Distortion Theorems for Harmonic Mappings
Bulletin of the Malaysian Mathematical Sciences Society, 2023 We establish two-point distortion theorems for sense-preserving planar harmonic mappings $f=h+\overline{g}$ which satisfies the univalence criteria in the unit disc such that, Becker's and Nehari`s harmonic version. In addition, we find the sharp two-point distortion theorem when $h$ is a convex function, and normalized mappings such that $h(\D)$ is a $

Measurement of nonlinear and Doppler distortion in Distributed Mode Loudspeakers [PDF]
International Journal of Electronics and TelecommunicationsDistributed Mode Loudspeakers (DMLs), as other electroacoustic transducers with electrodynamic excitation, are susceptible to the occurrence of nonlinear distortion. The literature on nonlinear distortion in DMLs is scarce.
