Gaussian noise refers to a type of statistical noise that has a probability density function (PDF) equal to that of the normal distribution, also known as the Gaussian distribution. This type of noise is characterized by its bell-shaped curve, which is symmetric around the mean. ### Key Characteristics of Gaussian Noise: 1. **Normal Distribution**: Gaussian noise is described by its mean (average value) and standard deviation (a measure of the spread or variability).
