Reducing Crosstalk
Crosstalk occurs if a signal with steep edges runs close to a high
impedance analog signal. The main reason for crosstalk is inductive
coupling. It can be reduced by the following measures:
n
Twist each signal line with its return line (ground).
n
Never twist two signal lines.
n
Separate digital and analog signal lines. Keep fast
‑
changing signals
far away from analog inputs.
n
Avoid connecting high
‑
impedance sources to the inputs of the
dSPACE boards.
n
If you use multiconductor cables, the individual twisted pairs
should be shielded.
n
