Which one of the following statements regarding compandor is FALSE?

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