oh, sorry for confusing you...... I adjust the singnals a little bit strange!
the 2 stripes at the bottom are the low signal and the 2 top stripes are the high signal. I have 6 different signals one after another with a little bit time between, and after maybe 500 milisecs the same again. At the picture are 3 of them..... (little bit difficult without a memory scope).
In this signals must be a temperature information I like to filter out....
