The matte-black circuit board that holds Tristan Perich’s Noise Patterns has a few things in common with your average smartphone. It’s small and sleek enough to fit into your pocket, and it comes with ...

Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...

Testing digital designs usually requires one or more digital signals, some of which can be very difficult to generate. Pattern generators are specifically designed to address this problem. Whatever ...

Whether you design communications equipment, develop tests for production, install network subsystems, or maintain fnetworks, you need to make bit-error-rate (BER) measurements. BER measurements give ...

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 ...
