Computes the continuous Gabor transform with Gaussian window.

1 |

`input` |
input signal (possibly complex-valued). |

`nvoice` |
number of frequencies for which gabor transform is to be computed. |

`freqstep` |
Sampling rate for the frequency axis. |

`scale` |
Size parameter for the window. |

`plot` |
logical variable set to TRUE to display the modulus of the continuous gabor transform on the graphic device. |

The output contains the (complex) values of the gabor transform of the input signal. The format of the output is a 2D array (signal\_size x nb\_scales).

continuous (complex) gabor transform (2D array).

freqstep must be less than 1/nvoice to avoid aliasing. freqstep=1/nvoice corresponds to the Nyquist limit.

See discussion in text of “Practical Time-Frequency Analysis”.
