Is BER the bit error ratio or the bit error rate?

As pointed out in the comments section of my previous blog post, Tx BER testing can only go so far in predicting the BER of a system. For rigorous Rx testing, a PG ...

Bit-Error-Rate Testers Face Ethernet Speed Challenges

This file type includes high resolution graphics and schematics when applicable. The bit error ratio (BER) is defined as the probability that a bit is received in ...

The difference between BER and BER

In 2013, I posted a poll on DesignCon Community—the predecessor to DesignCon Central—asking which definition for BER engineers used. The choices were bit-error ...

Eye Diagrams, Bathtub Curves, And Bit-Error Rates

On an oscilloscope's eye-pattern diagram, the distance between peak deterministic and random jitter amplitudes (the unit interval, or UI) is often called a "bathtub," which functions as a ...

FPGA-Based Bit Error Rate Performance Measuring of Wireless Systems

The proposed BER Tester (BERT) integrates fundamental baseband signal processing modules of a typical wireless communication system along with a realistic fading channel simulator and an accurate ...
