I've been working on a system that needs to measure a changeable number in a confined space (The space doesn't really matter) and I was struggling to find a way to do so. I am thinking about measuring signal strengths, but I can't find a way to increase the signal strength by a changeable number. Any ideas?

(Edit) - More details on the system:

- The input is a strength of 1, although it doesn't necessarily have to be.

- The system's goal is to take in 8 inputs, determine how many are on, and output a signal strength equal to that number (For context, it will then take that number and will apply some logic to it to do stuff).

- The size would preferably be as small as possible, but that (again) does not really matter.
