This circuit has been taken from a "DIY Oscilloscope" project. This circuit is changing the input wave swing to 0V to 3.3V. The circled voltage source is Vsys/2, which is the voltage at which the zero level of the input wave will be shifted to. Vsys is 3.3V here.
The output is as follows:
I wanted to know how is this working and can I use it for my project?
The original circuit with Raspberry PI PICO is as follows.
Thank you.
Sudeep AJ Ok, here we go. I hate to do this but, did you figure out what bandwidth you need? I noticed that you limit your voltage to 3.3v which by the way is a FLOATER in TTL. I personally think you are going to have a toy when you're done.
Save the sweat, money, and time and pick up a good used scope. You can pick one up like my old Tektronix 475A for about 150 bucks plus shipping. I have inserted the first
a paragraph from the manual. 
Please note that I can see 1ns/div which I do use when I have noise transits from things like Switches, Keyboards, and Relays. In other words any contactor.
If you go through this exercise remember that the front end is ANALOG and therefore near RF frequencies, and EVERYTHING MUST BE SHIELDED. Also, my probes (Tektronix) have a built-in compensator as well as a 10:1 divider, and they're good to 500 MHz.
Please enjoy the project just keep some of my wisdom in your mind. ~~ CAH
