Question

Equalization is linear if an analog signal is fed back to change the subsequent outputs of the equalizer.

(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

The above asked question is from Equalization Techniques topic in section Equalization, Diversity and Channel Coding of Wireless/Mobile

Answer 1

Correct option is (b) False

To elaborate: If the analog signal is not used in the feedback path to adapt the equalizer, the equalization is linear. On the other hand, if it is fed back to change the subsequent outputs of the equalizer, the equalization is non-linear.
