WebThe filter coefficients are most likely calculated in floating point format and must be converted to 16-bit fixed point. The format used by the FMAC is q1.15, which means that bits 0 to 14 represent fractional digits (ie. to the right of the binary point), while bit 15 represents the sign/integer. Q1.15 format can therefore represent numbers in the 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.
