WebAdvanced Frequency and Time Domain Filters for Currency Portfolio Management By Christian L. Dunis∗ and Jia Miao∗∗ (Liverpool John Moores University and CIBEF∗∗∗) August 2005 Abstract The first motivation of this paper is to study the existence of cyclical properties among FX markets with the use of spectral analysis. WebChebyshev filters are used to separate one band of frequencies from another. Although they cannot match the performance of the windowed-sinc filter, they are more than adequate for many applications. The primary attribute of Chebyshev filters is their speed, typically more than an order of magnitude faster than the windowed-sinc. This is ...
