~~~~~~~~~~~~~~~~~~~~~

   :width: 48


Generate a Table with signals like sine, cosine, etc., with or without random noise.



**Documentation**

Available signals are currently sine, cosines or tangent.

Noise
-----
If 'Add random noise' is checked, random white noise with the specified
amplitude will be added to each signal.


**Definition**


*Input ports*


*Output ports*

    :port0:  table

        Signal Table



*Configuration*:
    **Column entries** (column_entries)
        The number of column entries to be generated.
    **Column length** (column_length)
        The length of columns to be generated.
    **Signal type** (signal_type)
        The signal to be generated.
    **Amplitude** (amplitude)
        The amplitude of the signal to be generated.
    **Frequency** (frequency)
        The frequency in inverse samples of the signal to be generated.
    **Period** (period)
        The period in samples of the signal to be generated.
    **Period or Frequency** (use_period)
        Use Period [Checked] or Frequency [Unchecked] to generate the signal.
    **Phase offset** (phase_offset)
        Phase offset in radians of the signal to be generated.
    **Add random noise** (add_noise)
        If random noise should be added to the signals.
    **Amplitude of noise** (noise_amplitude)
        The amplitude of the noise.
    **First column as index** (index_column)
        Add an index column to the beginning of the table.
