Заголовок статьи: Scaling recursive of digital filters with nonrecursive lateral feedbacks


The article states ways to scale digital filters (DF) with lateral feedbacks (LFB). Models of four types recursive of DF with LFBs with their nonrecursive implementation are considered. Filters are scaled using hi impulse response and scaling using the amplitude-frequency characteristic of the circuit. The obtained results allow, on the one hand, to prevent overfilling of the grade graticule of the DF with LFBs, and on the other hand, to significantly increase its noise immunity and efficiency.
