Frequency content and autocorrelation function of noisy periodic signals
D. Villani, R. M. Ghigliazza, R. Carmona
We extract the frequency content of a noisy signal by use of Discrete Fourier Transform. Our analysis overcomes the limitations imposed by incommensurate lattices. After computing…

R. Carmona, L. Koralov, S. Molchanov
We find the asymptotics for the almost sure Lyapunov exponent for the solution of the parabolic Anderson problem as the molecular diffusivity tends to zero.
