摘要: The paper presents a procedure of approximate implementation given fractional-order system as an electronic analogue active filter. Employment LIRA method impulse response approximation allows the filter to be only composed standard RC components and operational amplifiers. A proposed state variable transformation helps simplify structure reduce component count while improving its noise properties accuracy integer-order prototype frequency reproduction. provides compares results realistic LTspice IV simulations for both implementations based on realisation transfromed variant respectively. They confirm effectiveness presented approach involving steps.
