Performance analysis of multi-rate signal processing digital filters on FPGA
EURASIP Journal on Wireless Communications and Networking, 2019 Multi-rate signal processing, an important part of the design of a digital frequency converter, is realized mainly based on interpolation and decimation, which match the sampling rate between the baseband and high-frequency processing side, especially in

Medical image enhancement using threshold decomposition driven adaptive morphological filter [PDF]
, 2008 One of the most common degradations in medical images is their poor contrast quality. This suggests the use of contrast enhancement methods as an attempt to modify the intensity distribution of the image.

Realisation techniques for primitive operator infinite impulse response digital filters [PDF]
, 1993 This paper presents realisation techniques for IIR digital filters based on the primitive operator graph synthesis method. The approach exploits the redundancy present in the filter multiplier structure when the coefficients are invariant allowing ...

Gate level optimisation of primitive operator digital filters using a carry save decomposition [PDF]
, 1994 This paper introduces a method for optimising digital filter realisations at the gate level. The method is based on a derivative of the primitive operator approach of Bull and Horrocks which is extended using a carry-save decomposition of the primitive ...
