Abstract :
The truncation of binary numbers can be modeled as noise and a DC-error if certain conditions are fulfilled. These truncation effects in finite impulse response (FIR) digital filters that are realized with canonic signed-digit (CSD) representation are reviewed. Three different techniques to reduce or eliminate the DC-error are presented and compared with respect to hardware and power consumption requirements
