very good info in the forum. another interesting application (which uses the exact inverse principle)of the above method is the oversampling technique used to increase the resolution of the ADC. this is well explained in AVR application note AVR121. It uses oversampling to increase the resolution for its inbuilt adc from 10 bit to 16 bit by introducing a fixed noise source. It could well be used in slower systems like temperature but the ADC conversion should be really fast.check this file out
