I modified the interpolator.
Look at Blatt 7
I made a switch interpolator on/off.
Then I took a flip flop negativ edge triggert
and put signal a (Blatt 10 left monostable pin 13 Q)
and delayed signal b not (Blatt 5 LS14 pin4)
to trigger it. With the output I switch the interpolator.
So there are no losses in vertikal resolution, Jeffrey
told about.
Only line three and one are added and not every
following line.
