This is not true- higher sample rates are just as effective in reducing 
overload as higher bit resolution.  The higher sample rates reduces the 
probability of multiple signals happening at the same time and overloading the 
ADC.  In addition, the higher rate allows for capturing smaller increments in 
signals and as the delta becomes smaller you need fewer bits.
