One interesting statistic is that signal integrity issues can account for up to 70% of overall system failures, highlighting the importance of addressing these problems effectively.
To identify the root causes of signal integrity problems, you need to analyze the waveform using your oscilloscope. Look for anomalies such as ringing, overshoot, or reflections that can degrade the signal quality. Additionally, check for impedance mismatches or noise sources that may be causing the problem.
Once you’ve identified the root causes, you can implement effective solutions to resolve the signal integrity issues. This may involve adjusting termination resistors, improving grounding techniques, or using signal conditioning techniques such as equalization or pre-emphasis.
By effectively resolving signal integrity problems, you can improve the performance and reliability of your embedded system, ensuring that it functions as intended.
