Approximaton as low-denominator rationals

I wonder if it makes sense to represent signals as low-denominator
rational values to avoid making low-frequency correlations?

Probably not, since necessary time-variance probably introduces such
correlations.  Might make nice pictures though..

EDIT: Maybe it is useful simply because there is a closed form
expression of the bit sequence for piecewize approximation of
low-denominator rational numbers.
