Fundamental properties of non-negative impulse response filters — Theoretical bounds II
Y. Liu, Peter H. Bauer · 2009
This paper presents fundamental limitations imposed on the frequency response of a filter by a non-negative impulse response (NNIR). Several upper-bounds on power spectral attenuation/gain in linearly spaced frequency regions are derived. These upper-bounds serve as a guide in the design of NNIR filters.
