High-Performance Digital Filters
Digital filters, both finite impulse response (FIR) and infinite impulse response (IIR), are widely used in many applications. The motivation for this work lies in the importance of developing methods to reduce the complexity in implementing these types of filters.

PIC 18F452 implementation of digital filters
… the designing and implementation of two types of filters for the PIC 18F452 microcontroller. The main purpose of this research is to implement a floating-point least mean square (LMS) error adaptive filter and its secondary goal is a fixed-point implementation of finite impulse response (FIR) …

Iterative design of l(p) digital filters
The design of digital filters is a fundamental process in the context of digital signal processing. Being essential building blocks, digital filters are used in diverse areas ranging from medical imaging or audio and video processing, to highly sophisticated military applications (among many …

Suppression of Limit Cycles in Digital Filters
… cycle oscillations in second-order direct form digital filter sections is discussed. Three types of dither signal are used: uniformly distributed random dither, binary randan dither and bandstop dither. All the limit cycles in the second-order filter sections can be suppressed by the injection …

ANALYSIS AND DESIGN OF PERIODICALLY TIME-VARYING DIGITAL FILTERS
… was developed. New criteria for designing the filters with decimator-interpolator structures were derived. With these new design criteria more efficient filters were designed. When these techniques were applied to filters with highly quantized coefficients that dither or vary periodically with …

Frequency sampling digital filters for multirate applications and pipelined implementations
… certain circumstances, narrowband linear phase filters can be implemented more efficiently using frequency sampling filters than direct convolution filters. The desired frequency response of a frequency sampling filter is approximated by interpolating a frequency response through a set of …

Study of circularly symmetrical two-dimensional digital filters possessing separable denominator transfer functions
… presence of circular symmetry in such designed filters by parameter modifications. In keeping with the simple design criteria, the two-dimensional filters studied in this thesis have been designed starting from two one-dimensional filters as an independent product. Only IIR Filters have been …
