Electromagnetic Interference (EMI) is essentially invisible noise or pollution. It is unwanted electromagnetic energy generated by one electronic device that disrupts the normal operation of another nearby device. This FAQ will explain what an EMI is and what are the ways to prevent it. This interference does not just travel in one way. Figure 1 […]
How are NRZ and PAM different in an eye diagram?
Eye diagrams are important tools in telecommunications for analyzing the performance of digital signals, such as noise, distortion, and intersymbol interference. This FAQ compares the non-return-to-zero (NRZ) and pulse modulation (PAM) formats, which are common ways of reading an eye diagram. NRZ represents binary data using two voltage levels, 0 and 1. This results in […]
What information does an eye diagram depict?
An eye diagram is a powerful visualization tool in digital communications and high-speed electronics to assess signal quality and channel performance. This FAQ will briefly explain an eye diagram and the overall and specific metrics engineers should know to understand an eye diagram. When capturing signals from a digital bitstream such as Ethernet or USB, […]
