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

The circuit is always biased in class C, by virtue of the leak-type bias.
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 output must be tuned

In a ratio detector

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