Generate Signal Tables¶
To generate data fast and easy is valuable when you want to test the functionality of nodes or during the development process of nodes. In Sympathy random data can be generated for both Tables and ADAFs, both a single object or as a list with several objects. The random data consists of random floats in the half-open interval [0.0, 1.0). The Generate Signal Nodes allow the generation of sinus, cosines or tangent signals with or without added random noise.
The properties of the outgoing objects are specified in the configuration of the nodes. For example for ADAFs, it is possible to specify the number of signals in the various containers, how many attributes will be connected to each signal or the number of elements in the signals. Similar properties can be specified for Tables, where far less alternatives are given.
Generates a list of tables with signals like sinus, cosinus, etc.
- File : Table
Table with signal data.
- Table list length
Specify the number of Tables in the created list.
- Column entries
Specify the number of columns in the Table.
- Column length
Specify the length of the columns in the Table.
- Signal type
Specify the function type to generate the signal. Currently supported are sinus, cosinus and tangent.
Specify the amplitude of the signal.
Specify the frequency of the signal.
Specify the period of the signal.
- Period or Frequency
Specify if either the period or the frequency is used to generate the signal.
- Phase offset
Specify the phase offset of the signal.
- Add random noise
Specify if random noise should be added to the signal. See also Amplitude of noise.
- Amplitude of noise
Specify the amplitude of random noise added to the signal, when Add random noise is selected.
- First column as index
Specify if the first column should be an index column.
