Utilize analog and digital signal processing techniques in building a low-cost high-precision digital oscilloscope for high ...

He wanted to improve on the design though, making a smaller unit with a greatly reduced bill-of-materials and with a more streamlined design, so he came up with this STM32-based oscilloscope.

At the budget end of the oscilloscope range lie the so-called ... and an effort to design a better input circuit. At its simplest this could be a straightforward op-amp and ADC circuit feeding ...
