Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier.
The directive gain gd, in a given direction is defined as the ratio or radiation intensity in that direction to the average radiation intensity, Often the directive gain is expressed in decibels as. (4). Clearly, gd or G d is a function of direction (Î¸,Ï). Maximum directive gain is called directivity.
