There are Forum members who were using film when it was rated in DIN.
I'd be curious to know if anyone remembers some of the other older rating systems like Weston, BSI, or GOST. (There are probably some residents of the former Soviet Block here who used GOST.)

Answering as not a DSLR engineer, I've never heard of signal amplification as a method. I'm guess that would mean either boosting the power into the sensor or running it through a booster afterward to increase the signal. I suppose that could have benefits for signal-to-noise ratio. So, maybe? I have always heard of ISO increases as being a software solution, but that doesn't mean that I'm right.
