Capacitive coupling |
摘要 |
A capacitive coupling arrangement including a plate-shaped input/output terminal of a signal line and a plate-shaped input/output terminal of a price display unit. These input/output terminals are connected together separated by a small gap and the respective input/output terminals are capacitively coupled. Amplifiers are connected to the input/output terminals as necessary to amplify the signal being transmitted across the capacitive coupling.
