Chapter 13: Problem 1

In a zero-level detextor, the otiput changes stute when the input \(\begin{array}{llll}\text { (a) is positive } & \text { (b) is negutise } & \text { (c) crosses zaro } & \text { (d) has u zero rafe of change }\end{array}\)

Short Answer

Expert verified

The output of a zero-level detector changes state when the input \( crosses \) zero. The correct option is (c).

Step by step solution

Understand the zero-level detector's main function

A zero-level detector is designed to detect when an input signal crosses the zero level, that is, when it changes from positive to negative or from negative to positive.

Select the correct option

Based on the function of the zero-level detector described above, we can select the correct option: Option (c) when the input crosses zero. So the output of a zero-level detector changes state when the input crosses zero.
