"WebFP of fixed-point IIR filter in direct form. From Figure L5-19 , the magnitude response of the fixed-point version of the IIR filter is seen to be quite different than its floating-point version. This is due to the fact that one underflow and one overflow occur in the filter coefficients, causing the discrepancies in the responses. " - Fixed point iir
