Which of the following is specified by a specific number of bit errors occurring in a given transmission?

Solution (By Examveda Team)

Bit Error Rate (BER) is defined as the ratio of the number of bits received in error to the total number of bits transmitted during a specific period.

The question asks which option is specified by a specific number of bit errors in a given transmission. The correct answer is Option C: Bit Error Rate.

BER directly relates the number of bit errors to the total number of transmitted bits. A higher BER indicates a worse communication channel quality, with more errors occurring during transmission.

Let's look at why the other options are incorrect:

Option A: Equally likely event refers to a situation where each possible outcome of an event has the same probability of occurrence. This is a probabilistic concept and doesn't directly define a specific number of bit errors.

Option B: Exhaustive events describes a set of events where at least one of the events *must* occur. This is also a general probabilistic concept, not directly tied to a count of bit errors.

Option D: Outage event refers to a situation where the signal quality falls below a predetermined threshold, rendering the communication link unusable. While an outage event often *results* from a high bit error rate, it's not directly defined by a *specific* number of bit errors. An outage is triggered when the BER exceeds a certain level, but it doesn't describe a specific number of bit errors itself.
