Заголовок статьи: Scaling of digital filters with lateral feedbacks

Резюме

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

Keywords: recursive digital filters, recursive lateral feedbacks, scaling, maximum signal limiting, maximum signal energy, maximum amplitude-frequency characteristic of the cir-cuit.
