Abstract
An apparatus includes a plurality of delay elements, a plurality of multipliers and an accumulator to form a biquad stage; and a precision logic circuit. The biquad stage includes feedback paths; at least one feedback path has an adjustable bit precision; and the precision logic is adapted to regulate the bit precision of the feedback path(s) based at least in part on at least one parameter that is associated with the biquad stage.
