Low-sensitivity universal first-order digital filter sections without limit cycles
I.P. Topalov, Georgi K. Stoyanov · Electronics Letters · 1990
Two new universal digital structures simultaneously realising at different outputs all types of first-order filter transfer function (lowpass, highpass and allpass) are proposed. The structures use a canonical number of multipliers and delays, are limit-cycle-free and with low sensitivities, and are convenient for VLSI implementation of universal chips.
