  • Abstract
    Variable coefficient wordlengths in combination with a multiplier reduces the computational complexity of fixed-point IIR digital filters with minimax error specification. When variable wordlengths are used for the least-squares error specification here, improved filters are achieved without resorting to discrete optimisation. Also. The wordlength allocation for the least squares criterion gives near-optimum results for filters with minimax specification
