Is T associated with E1 or E2? I think it is E2.

To determine whether T is associated with E1 or E2, we need to understand the context in which these terms are being used.

T (Higher Order Equivalent Time), E1, and E2 are typically associated with high-speed digital communication systems and are used to measure the performance of a system in terms of error rates.

E1 refers to the number of bit errors per second in a communication system, while E2 represents the number of error events per second. Both E1 and E2 are used to quantify how well a communication system is functioning.

T, on the other hand, is a measurement that characterizes the duration and severity of errors in a high-speed digital communication system. It provides information about the type of errors occurring, such as single bit errors, burst errors, or error-free intervals.

Given this information, T is not directly associated with E1 or E2. It is a separate measurement that complements E1 and E2 by providing more detailed information about the error patterns in a communication system.
