==Single channel systems==

In a single channel communication system the deamplification and loss present on them can be simplistically taken as attenuation by a percentage ''g'', then amplifiers restore the signal power level to the same value at transmission setup by operating at a gain of 1/ (1-g). E.g. if we experience 6dB6 dB attenuation in transmission, i.e. 75% loss, then we have to amplify the signal by a factor of ''4x'' to restore the signal to the transmitter levels.
