The Ricker wavelet, also known as the Mexican hat wavelet, is a popular representation of seismic signals. The Ricker wavelet r(t) is defined as the second derivative of the Gaussian
r(t)=−d2dt2g(t), where g(t)=e−a2t2.
(a) Find and plot the Fourier transform of the Ricker wavelet.
(b) Find the peak frequency: the frequency of the maximum of the Fourier spectrum.
(c) Find the apparent frequency: the frequency corresponding to the period between two minima in the time domain.

http://ask.sagemath.org/question/24772/find-and-plot-the-fourier-transform-of-the-ricker-wavelet/?comment=24853#post-id-24853@tmonteil so how do I plot it? I don't know what function to use to plot it.Wed, 12 Nov 2014 19:44:05 -0600http://ask.sagemath.org/question/24772/find-and-plot-the-fourier-transform-of-the-ricker-wavelet/?comment=24853#post-id-24853Comment by tmonteil for <ol>

http://ask.sagemath.org/question/24772/find-and-plot-the-fourier-transform-of-the-ricker-wavelet/?comment=24774#post-id-24774This looks like homework. If you want some help, you should ask more precise questions related to your research in solving those exercises, especially where you are locked.Tue, 04 Nov 2014 01:46:21 -0600http://ask.sagemath.org/question/24772/find-and-plot-the-fourier-transform-of-the-ricker-wavelet/?comment=24774#post-id-24774
