Greater limiting
Better linearity
Fewer tuned circuits

Radio Receivers
In a radio receiver with simple AGC

The faster the AGC time constant the more accurate the output
The highest AGC voltage is produced
An increase in signal strength produces more AGC
The audio stage gain is normally controlled by the AGC

Radio Receivers
In a ratio detector

the linearity is worse than in phase discriminator
stabilization against signal strength variations is provided
the circuit is the same as in a discriminator, except that the diodes are reversed
the output is twice that obtainable from a similar phase discriminator
