and on that good response, it's time to close the thread
@michael1978 it really is time you started to read up and learn the basics of electronics
Start studying what each component does ... resistors, capacitors, diodes etc
read the LTSpice info in the link Harald gave you
You really must start to make a serious personal effort to learn the basics
That way, you wouldn't be asking such basic questions that I see in your threads here and on other forums
It will also make helping you a lot easier when everything doesn't have to be explained to you from square one
You have already been banned on at least one other forum. It would be in your best interests not to let the same happen here
