A transmission method

To go from a coupled high level to the decoupled low level, the source unit (SU) of the transmitter (T) must be decoupled from the transmission line (TL) by the impedance unit (IU). As a result, oscillatory transition phenomena appear in the output signal and this signal possibly goes beyond a presc...

Summary:To go from a coupled high level to the decoupled low level, the source unit (SU) of the transmitter (T) must be decoupled from the transmission line (TL) by the impedance unit (IU). As a result, oscillatory transition phenomena appear in the output signal and this signal possibly goes beyond a prescribed template. To avoid such overshoot problems the present transmitter (T) decreases the signal level during a decrease period before decoupling the source unit (SU) from the transmission line (TL). Therefore a source control circuit (SCC) is included in the control unit (CU) of the transmitter (T). This source control circuit (SCC) enables controlling the source level in such a way that the output signal level is decreasing.
