Digitally controlled "programmable" active filters
… is presented. The novel design is a cascade of second order sections that are individually programmed to achieve any filtering topologies. Two-binary words are used to control the pole frequency co p and selectivity Qp of each section independently. Each second-order section is a …

Speech Coder using Line Spectral Frequencies of Cascaded Second Order Predictors
… forward linear prediction using five cascaded second order sections - parameterized in terms of line spectral frequency - in place of the conventional tenth order filter. The line spectral frequency parameters estimated by the Direct Line Spectral Frequency (DLSF) adaptation algorithm are …

Finite state machine representation of digital signal processing systems
… model is developed and applied to first and second order canonic form filter sections. Comparisons are drawn between the gaussian optimised filter and the equivalent fixed point arithmetic filter. The performance of gaussian optimised filters under sinusoidal input signal conditions is …

X-ray microscope performance enhancement through control architecture change
The goal of this thesis is to apply control algorithms to improve the performance of nanopositioning devices used on the beamline in Advanced Photon Source (APS) at Argonne National Laboratory (ANL). A prototype device, better known as the Early User Instrument (EUI) was the subject of this work. …
