Sometimes you might want to simulate noisy environments, e.g. for testing an algorithm's robustness against noise. Therefore I implemented a short method for adding Additive White Gaussian Noise (AWGN) to a signal. The strength of the noise can be specified by a Signal-to-noise ratio (SNR).
Signal without noise:
Signal with noise (SNR=2):
Thanks to @superbock for the tip to use a fixed random seed for testing!
