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 WebThe second step towards a fixed point conversion of IIR filters consists of applying dynamic range analysis to the filter to fine-tune the scaling for each node.
