By applying the strategy of using as far as possible multiplier coefficients that are machine representable in conjunction with the wave characterization, a synthesis procedure is developed which yields low-sensitivity wave digital biquads. The procedure yields structures which can be stabilized with respect to zero- and constant-input limit-cycle oscillations. In addition, multiple-output structures can be obtained which realize simultaneously the standard second-order transfer functions. The paper includes experimental results which demonstrate that a low-sensitivity wave digital biquad based on the three-amplifier RC-active configuration is less sensitive than other known low-sensitivity digital biquads. © 1989 IEEE
