PV-WAVE's
Signal-Processing Toolkit is a broad selection of predefined and
customizable digital signal-processing functions designed to improve
your data analysis and simulations. Filters are transfer function-based
for easy design, analysis and realization of custom filters. The
toolkit includes functions and procedures for the Fourier and wavelet
analysis of a signal, as well as utilities and source code to facilitate
custom function development.
The Signal
Processing Toolkit includes numerous powerful functions, such as:
