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 ...

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 ...

As EDN has reported over the last two years, 56 Gbit/s links are moving to PAM4 signaling as a way to overcome channel bandwidth issues. As this modulation technique takes hold, you'll need to ...
