| 41 Spectral estimation is a branch of the signal processing, performed on data | |
| 42 and based on frequency-domain techniques.<br> | |
| 43 Within the LTPDA toolbox many functions of the Matlab <a href="matlab:doc('signal')" >Signal Processing Toolbox</a> | |
| 44 (which is required) were rewritten to operate on LTPDA Analysis Objects. | |
| 45 Univariate and multivariate technique are available, so to estimate for example the linear | |
| 46 power spectral density or the cross spectral density of one or more signals. The focus of the | |
| 47 tools is on time-series objects, whose spectral content needs to be estimated.<br> | |
| 48 More detailed help on spectral estimation can also be found in the help associated with | |
| 49 the Signal Processing Toolbox: | |
