Gaussian Modulated Sine Pulse for NDT

Predict Gaussian modulated sine pulse in time and frequency domain and compare their FFT and iFFT, respectively.

This code models the Gaussian Modulated Sine Pulse in time and frequency domains using their analytical expressions and also performe Fourier Transform and Inverse Fourier Transform for comparison. The analytical expressions are given in [1]. Download the files for description.
