Details

The chirplets described in this Demonstration are a generalization of sine-Gaussian signals. A sine-Gaussian signal is characterized by its central frequency and quality factor (ratio of central frequency to the bandwidth of the signal), whereas a chirplet is characterized by a central frequency, quality factor, and chirp rate [1]. Using chirplets in gravitational-wave burst searches has shown to increase detection efficiency compared to burst searches using a sine-Gaussian basis [2].
