EMC Concepts Explained

Crosstalk Reduction Between PCB Traces

The article explains crosstalk between circuit traces, showing how signals propagate between nearby conductors through capacitive and inductive coupling. It demonstrates experimentally how reducing separation distance and adjusting ground plane proximity affects near-end and far-end crosstalk voltages in PCB microstrip configurations.

Transmission Line Reflections at a Discontinuity

What happens when signals meet an impedance mismatch? Discover the elegant mathematics governing reflections and transmissions at transmission line discontinuities. Watch as voltage pulses navigate between different cable types, creating a predictable cascade of reflections that perfectly matches theoretical calculations.RetryClaude can make mistakes. Please double-check responses.
