The circuit diagram and eye diagram are shown. The eye diagram, one of the best figures of merit for evaluating robustness in a digital data link, shows a single bit window (bit N), preceded by a random-value bit (N-1) and followed by a random-value bit (N+1). Communications-systems engineers usually have access to the sophisticated test equipment required to measu……
