The path to a solution
To try to solve some of the problems caused by taking an inconclusive transform of a whole time series, Dennis Gabor developed Short-Time Fourier Analysis on windowed signals in 1946. However, this approach offered no variability to determine time or frequency more accurately in any particular window. Wavelet analysis was developed as a windowing technique which allowed forWavelet analysis has many benefits which make it a more applicable tool for analyzing the financial markets. This:
- uses long -time wavelet-analysis intervals for finding precise low -frequency information.
- uses short -time wavelet-analysis intervals for finding precise high -frequency information.
- performs local analysis, which allows us see frequency events at a specific times in a signal.
- works much better with non-linear signals.
