    I have set-up the attached circuit in multisim from an example ina book and I'm not getting a rectified wave at the output like I should.

    Can anyone tell me whats wrong with it?

    I thought I'd try to use the method out of the book. But it won't work. I seem to find theoretical info alot but I struggle to put it into practise. Can you see where I am going wrong?

    I have a hunch that you instead of trying to understand the principals. You just use google and then try to copy anything that you hope will work. That approach will never bring you far then it comes to engineering. If you aim at nothing you will hit nothing.

    I understand the principles in block form but I just dont know how to implement them in practise with an actual circuit.
