What is PCB Crosstalk? PCB crosstalk is a voltage noise phenomenon caused by inductive coupling or capacitive coupling between two signal lines. Types of Crosstalk According to different sources, there are three different types of crosstalk on the PCB: inductive coupling, capacitive coupling and common resistance coupling. inductive coupling Inductive coupling is a process of
What is Electromagnetic Interference (EMI)? Electromagnetic interference (EMI) is an undesirable phenomenon that can occur in any electrical circuit. It is generally caused by the presence of strong electromagnetic fields and has the potential to disrupt or interfere with the normal operation of sensitive electronics. If left unchecked, EMI can hurt the performance of electronic
