Noise, Signal detection, Hearing and speech Noise, spectrum level and band level — combing band levels and tones — detecting signals in noise — detection threshold — the ear — fundamental properties of hearing — loudness level and loudness — pitch and frequency compiter voice.

This also covers small propagation effects such as fading, time delay spread and Doppler spread and describes how to measures and model the impact that compuuter bandwidth and motion have on the instantaneous received signal through the multi-path channel. This also demonstrates the principle of trunking efficiency and how trunking and interference issues between mobile and base stations combine to affect the overall capacity of cellular systems.
