Noise addition in post-processing

CIVA allows for the addition of background noise to simulated results by using a simple post-processing operation. This type of noise has no direct link to a physical phenomenon; it is random noise added to simulated signals to make them more realistic.

To use this tool, simply select the “Noise Addition” post-processing option once you have run your simulation, as shown in the screenshot below.

Once you have selected this tool, all you have to do is set the noise level in “points”. For example, if the maximum of your simulation is 16 points and you set the noise level to 1 point, you will obtain a signal-to-noise ratio of approximately -24dB. The image below illustrates the result of this post-processing.
