So this underpins a project you'll hear about later.
Assuming a linear dimming curve, and ignoring the triac issues around the zero crossings, what's the relationship between the inputs to a dimmer (be it DMX or analogue) to the output?
Should a control input of 33% result in the RMS output voltage being 33% of the unadulterated input? Or is it that it should represent a 33% duty cycle, ie. that 33% of the time, the voltage is being output?
