Re: Equivalent time-and-bit-depth sampling?
In dithering the signal still only makes the signal traverse roughly one
least significant bit of headroom - in my case it would traverse the whole
headroom between the captured voltage (+overshoot) and zero. That is the
property I thought would bring an advantage. In addition it does so
"slowly", i.e. nearly all of this traversal happens at very low slew rates
compared to the slew rate of the high frequency components of Gaussian
noise, which in turn means you are not limited by the performance of the
ADC near Nyquist, and don't need to worry about aliasing as much. I believe
this could be another advantage.
