DESIGN PROCEDURE FOR TUNABLE NARROW-BAND DIGITAL FILTERS

A Novel Implementation for Narrow-Band FIR Digital Filters

In the cascade realization of fixed-point digital filters underdynamic range constraints, the output noise due to accumulation ofroundoff errors is highly dependent upon the order of the sections.For recursive filters it also depends on the pole—zero pairing that formsthe individual second-order sections. The output noise may vary overseveral orders of magnitude for differen...

Tunable Wideband Graphene based Filters in THz Band

In this paper, a procedure for analyzing and designing of tunable wideband band-pass and band-stop graphene based filters in the terahertz band is proposed. These planar wideband plasmonic filters are unique in their kind. With this procedure, it is possible to design filters with the desired functional characteristics in the form of the similar quarter-wavelength resonance stubs. The discontin...

Implementation of Narrow-band Lattice Wave Digital Filters

Recently, a filter structure for narrow-band filtering based on lattice wave digital filters was introduced. The structure has increased parallelism over the corresponding direct realization. In this paper, hardware implementation of the filter structure is discussed. The suggested approach uses bit-serial processing elements that are scheduled so that a maximally fast implementation is achieve...

Characterization of Narrow Band Filters for

We present a characterization of two narrow band lters commonly used in Infrared Astronomy. Our study mainly quantiies the eeect of temperature and tilt angle on the central wavelength and width of the transmission bands of such lters. This allows to evaluate some important eeects that must be taken into account to have good quality astronomical images. EEects as the limitation of the eld of vi...
