Nice, and I know that I'll use it one day, but this is not exactly 
what I meant. Digital signals (in the sense of the digital signal
processing) are not defined during the intervals between two samples. 
So there must not be a line drawn on the horizontal axes. Do you 
have an idea for this? Maybe it needs just a modification of your 
'digital signal' ...

Thanks,

Jürgen
