Stochastic Variance Distribution Spectral Density

This document discusses noise and how it can be quantified. White noise has equal power across all frequencies. Decibels (dB) relate to voltage and power in a logarithmic scale and are used to measure noise. Noise is a stochastic process with stochastic properties like variance, distribution, and spectral density.
