Signal Processing and Analysis

Dynamic Systems Toolkit (DST) is a part of Perun PowerDesk responsible for live signal processing and signal analysis in general. Most of the toolkit’s functionality can be accessed easily by means of the Ribbon Menu. However, it is also possible (and sometimes even easier) to invoke the functionality using the Project Explorer.

Dynamic Systems Toolkit operates with two types of items: signals and spectra. Signals are quantities that depend on time. They can be measured or generated according to some pre-specified functional specification. Spectra are quantities that depend on frequency. A spectrum is always related to some signal, from which it is obtained by means of the Discrete Fourier Transform (more precisely by means of the FFT algorithm).

Each DST item is characterized by a unique name. Once an item is created, PowerDesk proposes some descriptive, default name to it. For example, if a signal is named Signal, then the corresponding spectrum is named Spectrum of 'Signal'. A similar naming convention is applied for other types of signal transformations.

The following processing and analysis tools are supported within PowerDesk:

• Adding custom signals
• Adding Static Signal Mappings
• Adding Binary Static Signal Mappings
• Adding Filtered Signals
• Performing Spectral Analysis
• Expression Syntax
