WVD Spectrogram PtByPt (Not in Base Package)

Computes the signal energy distribution in the joint time-frequency domain using the Wigner-Ville distribution algorithm.

initialize, when TRUE, initializes the internal state of the VI.
input data is a set of input data.
sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than zero.
time increment controls the time intervals of the Wigner-Ville Distribution. The default is 1. For example, if you sample the time waveform at fs Hz, the spacing between the rows of WVD Spectrogram {X} is time increment /fs seconds.

Increasing time increment decreases the computation time and reduces memory requirements but also reduces time-domain resolution. Decreasing time increment improves time-domain resolution but increases the computation time and memory requirements.

WVD Spectrogram {X} is a 2D array that describes the time waveform energy distribution in the joint time-frequency domain. The number of rows, time axis, in WVD Spectrogram {X} is equal to the number of elements in the time waveform divided by time increment and then rounded up.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.
