Demonstration of ideal lowpass filtering (with different bandwidths) of white noise using Matlab simulation. Estimation of power spectral density of stationary white noise using Matlab simulation.

Signal transmission with noise: baseband signal transmission with noise and additive noise and signal-to-noise ratios. Analog transmission: model of received signal with noise, total output power, signal-to-noise ratio, additive white gaussian noise, structure of the receiver of analog signal transmission, required signal-to-noise ratio at destination.
