Owning Palette: Utilities VIs

Generates a summation of Gaussian chirps with different parameters.

Example

samples specifies the length of the Gaussian chirp. The default is 128.
chirp info specifies the parameters of each Gaussian chirp.
 magnitude specifies the magnitude of the Gaussian chirp. phase specifies the phase offset of the Gaussian chirp in radians. standard deviation specifies the standard deviation of the Gaussian envelope in seconds. center specifies the central time of the Gaussian envelope in seconds. frequency specifies the central frequency of the chirplet in hertz. chirp rate specifies the sweep rate of the carrier sine wave in hertz per second.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
sampling rate specifies the sampling rate of the output signal.
Gaussian chirp returns the complex Gaussian chirps.
error out contains error information. This output provides standard error out functionality.
