What is Communication Systems: Power Measurement about?

This document discusses power measurements in communication systems. It defines power in dB units using the log ratio of the measured power to a reference value. Examples are given for converting between dBm, dBW, dBk units. It also covers gain, attenuation, signal to noise ratio and how to calculate output power given specified gains and losses over transmission lines. Noise sources and properties like white noise and noise spectral density are defined.
