As a key parameter for evaluating data transmission accuracy, the bit error rate directly determines the reliability and stability of communication systems. This article delves into the fundamentals and testing methods of the bit error rate. A bit error occurs when a single binary digit is flipped during transmission, meaning a logical '0' is mistakenly interpreted as a '1' by the receiver, or a '1' is read as a '0'. Through the interpretation of actual test reports, it. BER is calculated by comparing the transmitted sequence of bits to the received bits and then counting the number of errors. The ratio of how many bits received in error over the total number of bits received is the BER. This ratio is affected by many factors including: signal to noise, distortion.
