Optimization of Butterworth and Bessel Filter Parameters with Improved Tree-Seed Algorithm

open access: yesBiomimetics, 2023
Filters are electrical circuits or networks that filter out unwanted signals. In these circuits, signals are permeable in a certain frequency range. Attenuation occurs in signals outside this frequency range.

Electric circuit emulation of topological transitions driven by quantum statistics

open access: yes, 2021
Topological phases exhibit a plethora of striking phenomena including disorder-robust localization and propagation of waves of various nature. Of special interest are the transitions between the different topological phases which are typically controlled by the external parameters.

Improving the Signal to Noise Ratio of QTF Preamplifiers Dedicated for QEPAS Applications

open access: yesApplied Sciences, 2020
The signal-to-noise ratio (SNR) is a major factor that limits the detection sensitivity of quartz-enhanced photoacoustic spectroscopy (QEPAS) sensors. The higher the electrical signal level compared to the noise amplitude is the lower the concentration ...

Frequency response and gap tuning for nonlinear electrical oscillator networks. [PDF]

open access: yesPLoS ONE, 2013
We study nonlinear electrical oscillator networks, the smallest example of which consists of a voltage-dependent capacitor, an inductor, and a resistor driven by a pure tone source. By allowing the network topology to be that of any connected graph, such
