Webb14 nov. 2024 · We report the phenomenon of frequency clustering in a network of Hodgkin-Huxley neurons with spike timing-dependent plasticity. The clustering leads to a splitting of a neural population into a few groups synchronized at different frequencies. In this regime, the amplitude of the mean field undergoes low-frequency modulations, which may … Webb13 maj 2024 · Since the signal modulation amplitude scales as Fγ, this means that a smaller slow modulation amplitude γ will be necessary to overcome the hysteresis width and produce large jumps between the...
Webb18 aug. 2024 · After decades of advances, SLM arrays based on liquid crystals can now reach large pixel counts exceeding 10^6 with phase-only modulation with a pixel pitch of less than 10 {\mu}m and reflectance around 75%. However, the rather slow modulation speed in such SLMs (below hundreds of Hz) presents limitations for many applications. WebbMostly, FSK or MFSK modulation is used. Slow frequency hopping is a popular technique for wireless LANs. In GSM telephony, slow frequency hopping can be used, at the discretion of the network control software. It avoids that a stationary terminal that happens to be located in a fade looses its link to the base station. As ...
Webb26 maj 2024 · Normalizing wingbeat frequency modulation by these mean values results in normalized modulations of ±2.5%, ±16% and ±5%, respectively. In our two-factor ANOVA, we did find that individual moths had a weak effect ( p < 0.01, η 2 = 0.12) and individuals had different patterns of frequency modulation (interaction term; p < 0.01, η 2 = 0.18). Webb15 feb. 2024 · A lower limit can be estimated from the slow-modulation limit assumption of a fluctuation frequency much smaller than the linewidth. With the SDs in the range of 300 cm −1 observed for the lines here, this implies fluctuations that are much slower than a few hundred femtoseconds––in the general domain of low-frequency acoustic phonons, …
