Abstract :
A digital filter is a basic building block in any digital signal processing (DSP) system. The simulation results presented show how finite bit precisions can affect the performance of a digital filter. IIR filters are shown to be even more susceptible to finite bit precision effects than FIR filters. However, these effects can be reduced using the IIR filter with a cascaded structure
