Engineering, University of Western Australia.

2. WINDOWING – SHORT TERM FOURIER TRANSFORM

3. No Differentiation of Process by occurrence in time or frequency
Domain. Purely stochastic process.

4. Simple analysis of Time Series with break down of time
periods but no break down of frequencies within each group.

5. Tallahassee Monthly Precipitation
Simple analysis of frequencies over spectrum periods but
no break down of time and changing frequency characteristics.

6. Breakdown of spectrum of frequencies over discrete time periods.

8. Various frequencies or “scales”applied repetitively over appropriate
(to “scale”) time periods.

9. Basic wavelet form applied over various time scales by “extending” and
“compressing” wavelet over different time periods observations. Compression/ extension
Being analogous to various periods of oscillation.
