Question
a.
It compresses the higher-amplitude parts of a signal before modulation and expands them back to normal again after demodulation.
b.
It gives preferential treatment to the weaker parts of the signal
c.
For weaker signals it gives a poor ratio of signal strength to quantizing error
d.
Weaker signals, traverse more quantum steps than they would do otherwise and so quantizing error is reduced.
