I am a university student and would really appreciate your instructions/help on my project. I have a device with following output: 100ns duty cycle, Frequency is 100 Hz (means in each 10 ms I have only 100ns duty cycle) and pulse amplitude from 2 to 5 Volt. I need to convert this almost square pulse to digital to use in FPGA to control the pulse amplitude. For example if it goes higher and lower of a specific amount the FPGA should react.
I would really appreciate your kind instructions on the Analog Digital conversion part. If you need more information please let me know.
