designing a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Von Neumann was not a Quantum Bayesian.
Wikipedia has claimed for over 3 years now that John von Neumann was the 'first quantum Bayesian'. In context, this reads as stating that von Neumann inaugurated QBism, the approach to quantum theory promoted by Fuchs, Mermin and Schack.

متن کاملnot a fast rotator ⋆
We have investigated the nature of the magnetic white dwarf LP 790-29 = LHS 2293 by polarimetric monitoring, searching for short-term variability. No peri-odicity was found and we can exclude rotation periods between 4 sec and 1.5 hour with a high confidence. Maximum amplitudes of sinusoidal variations are ∆R < 0.009 mag and ∆V R < 0.7 % for a mean value of the R−band circular polarization of V...
