Abstract To improve the parameter estimation performance of damped real-value sinusoid in noise, a novel algorithm with high accuracy and computational efficiency is proposed that combines characteristics good anti-interference, small computation frequency-domain methods, time-domain methods. First, Discrete Fourier Transform (DFT) two-point spectrum interpolation methods are used to noise immu...

The digital transformation of electrical substations relies on the communication protocols introduced in IEC Std 61850. In particular, Sampled Value data format is expected to be employed an ever-increasing number measurement applications and devices. this context, National Metrological Institutes are required develop calibration infrastructures capable dealing with synchronous analog input out...

Abstract With the aim to solve time-dependent Schr ̈odinger equation associated a non-Hermitian Hamiltonian, we introduce unitary transformation that maps Hamiltonian time-independent PT -symmetric one. Consequently, solution of Schrödinger becomes easily deduced and evolution preserves C ( t ) -inner product, where is obtained from charge conjugation operator through time dependent transformati...
