I got this question during an internship interview.

I would like to ask this question from Equalization topic in section Baseband Demodulation and Detection of Digital Communications

Answer 1

The correct answer is (b) Width

For explanation I would say: An eye pattern is a display that results from measuring a system’s response to baseband signals in a prescribed way. The width of the opening gives the time over which the sampling for detection might be performed.
