noise from the sequence of nonoverlap** rectangular pulses

A Kononovicius, B Kaulakys - Physical Review E, 2023 - APS
We analyze the power spectral density of a signal composed of nonoverlap** rectangular
pulses. First, we derive a general formula for the power spectral density of a signal …

High-frequency current oscillations in charge-density-wave 1T-TaS2 devices: Revisiting the “narrow band noise” concept

AK Geremew, S Rumyantsev, B Debnath… - Applied Physics …, 2020 - pubs.aip.org
We report on the current oscillations in quasi-2D 1T-TaS2 charge-density-wave two-
dimensional devices. The MHz-frequency range of the oscillations and the linear …

[HTML][HTML] The discrete noise of magnons

S Rumyantsev, M Balinskiy, F Kargar, A Khitun… - Applied Physics …, 2019 - pubs.aip.org
We report experimental results, which show that the low-frequency noise of magnonic
devices is dominated by the random telegraph signal noise rather than 1/f noise—a striking …
