In this module, we consider the noise generated by the electronic devices themselves due to the random motion of electrons due to thermal energy. This added uncertainty in the voltages and currents limit the smallest signal amplitude or power that our circuits can detect and/or process, limiting the transmission range and power requirements for reliable communications.

Modeling Noise
Since electronic noise is random, we cannot predict its value at any given time. However, we can describe noise in terms of its aggregate characteristics or statistics.
