Radio Receivers
Show which of the following statements about the amplitude limiter is untrue:

The output must be tuned
When the input increases past the threshold of the limiting, the gain decreases to keep the output constant.
Leak-type bias must be used
The circuit is always biased in class C, by virtue of the leak-type bias.

Radio Receivers
In a radio receiver with simple AGC

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

In a ratio detector

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
the linearity is worse than in phase discriminator
