← ScienceWhich outcome results when stray capacitance couples digital lines?
A)Crosstalk causes unintended signal transmission✓
B)Impedance matching eliminates reflections entirely
C)Increased power supply ground isolation
D)Reduced electromagnetic interference emissions
💡 Explanation
When digital lines run close together unwanted changes in voltage will be coupled via parasitic capacitance, or capacitive coupling. This causes crosstalk because the signal induces a voltage on adjacent lines; therefore, unintended signal transmission will occur, rather than controlled signal transfer.
