hello circuit sits high pulse say 1.2v monostable ? Bistable ? it pulls down to 275 mv on scope and then pulls up again
what type of circuit would i use to implement new to electronics so forgive me regards dave

Welcome to AAC!

I don't understand what you're asking.

  1. What does "circuit sits high pulse" mean?
  2. What pulls down to 275mV? What is the device?
  3. What does it pull up to?

Welcome to AAC!

You can do it with RC and Schmitt trigger gates or you can use a monostable multivibrator circuit such as CD4528.

I understand that you're new to electronics, but that's still not an excuse for not answering all of the relevant questions.
Where's the picture?

Hello sir thank you I used a 2 diodes in series 0.8 1N1418 and germanium 0.2v however it lowers the resistance to much by 120 mv regards dave
