Generation of Gaussian White Noise, Colored Noise, and General Noise

This program is capable of generating three types of noise: Gaussian white noise, colored noise, and general noise, suitable for MATLAB simulation experiments. Gaussian white noise is a random noise characterized by a constant power spectral density and flat average power spectrum across all frequencies. Colored noise refers to noise with a power spectral density that is relatively uniform within specific frequency ranges. General noise encompasses any noise that does not fall into the categories of Gaussian white noise or colored noise. The flexibility of this program lies not only in its ability to generate different noise types but also in its parameter control features. Users can adjust key parameters such as power spectral density, frequency range, noise mean, and variance to meet the requirements of various simulation scenarios. The implementation utilizes MATLAB's built-in random number generation functions and signal processing tools to create realistic noise profiles with specified statistical properties.
