Bit Error Rate

Bit Error Rate (BER) is a measure used in digital communications to quantify the number of errors in transmitted data. Specifically, it represents the ratio of incorrectly received bits to the total number of transmitted bits. For example, if 1,000 bits are sent and 5 are incorrect, the BER would be 0.005, or 0.5%. A lower BER indicates better communication quality, meaning that data is transmitted more accurately. Understanding BER helps engineers evaluate and improve the reliability of communication systems, such as mobile networks and internet connections.
