Modelos de volatilidade estatística
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2008-08-22)
In the financial market usually notices are taken of the shares
sequentially over the time in order to characterize them a time
series. However, the major interest is to forecast the behavior of these shares. Motivated by ...
On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers
is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation
equivalent to an ...
Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
