A New Method for Ultra Fast Signal Processing and Pulse Generation in the Gbit/S Range.

A new sampling line with series gates is suited for both fast signal recording and fast pulse generation up to 10 Gbit/s as found in experimental results. It consists of a delay line with equidistantly inserted switches (in practice Schottky diodes). The spatial voltage distribution of a signal passing the delay line can discretely be stored on the delay line sections when the switches are opened e.g. simultaneously. The sampling line may function as a pulse or word generator, too. For that purpose the open ended delay line sections are charged to the amplitudes of a wanted output pulse shape before closing the switches. In order to achieve continuous signal recording resp. continuous pulse generation several paralleled sampling lines may operate successively, offering very promising ways to realize ultra high speed demultiplexers and multiplexers and a baseband repeater for the Gbit/s range.
