Which processing error arises when the clock data-recovery circuit in a high-speed fiber-optic receiver fails, causing incorrect sampling of the received signal?

💡 Explanation

Timing jitter significantly increases because phase errors in the recovered clock lead to variable sampling instants (sample at wrong points in the bit period), causing distortion; therefore timing jitter-induced distortion results, rather than simply noise, since the errors correlated errors with the data.
