Role of anticausal inverses in multirate filter-banks. I. System-theoretic fundamentals [PDF]

, 1995
In a maximally decimated filter bank with identical decimation ratios for all channels, the perfect reconstructibility property and the nature of reconstruction filters (causality, stability, FIR property, and so on) depend on the properties of the ...

The PEP Survey: Infrared Properties of Radio-Selected AGN [PDF]

, 2014
By exploiting the VLA-COSMOS and the Herschel-PEP surveys, we investigate the Far Infrared (FIR) properties of radio-selected AGN. To this purpose, from VLA-COSMOS we considered the 1537, F[1.4 GHz]>0.06 mJy sources with a reliable redshift estimate, and
