How can I sample a signal without ADC?

Hello,​ i have little experience in FPGA programming. My situation: I am an intern and eight weeks ago i had a fpga in hand for the first time. I am using the Polmaddie 7 DevBoard with a cyclone 10...

In short - you can't. FPGAs, on their own, don't (generally) had any ADC capability. MAX10 FPGAs do. However, depending on your signal - and particularly the scale of the noise on it - they're not likely to be sufficient to allow you to measure the noise.

Without some external circuitry or ADC you won't be able to determine an 'y-axis' behaviour beyond a logic high or low.
