ABSTRACT:
The present invention provides a transmission system having a signal source which has an internal resistance, having a signal transmission line (102), one end of which is connected to the signal source, and having a terminating resistance which is connected to another end of the signal transmission line (102), the internal resistance of the signal source and the terminating resistance being complex and being chosen such that frequency-dependent signal attenuation in the transmission system is reduced in a frequency range which contains the frequencies of signals which are produced by the signal source.
