Effective Power Signal Filtering Using LC Filters with Air Core Coils

Simulation of LC Ladder Filters Using Opamps

Implementing Cepstral Filtering Technique using Gabor Filters

Cepstral filtering technique is applied on an interlaced image, the pattern similar to that which is found in layer IV of Primate Visual Cortex. Unless the signals from left and right eyes are placed simultaneously, the disparity cannot be detected. Therefore, it has a great significance in the sphere of stereo vision. It involves Power spectrum in computation, which is square of absolute of Fa...

Testing Air-filtering Systems. I. Procedure for Testing High-efficiency Air Filters on Exhaust Systems.

A procedure was developed for evaluating high-efficiency filters mounted in exhaust ducts at the National Animal Disease Laboratory. An aerosol of the test organism, Escherichia coli B T(3) bacteriophage, was generated in a chamber attached to a ceiling exhaust register in concentrations of at least 1000 viable organisms per ft(3) of air. Samples were collected from both the pre- and postfilter...

Reducing Power in Multi-Core Network Processors through Data Filtering

We propose a data filtering method to reduce the power consumption of high-end processors with multiple execution cores. Although the proposed method can be applied to a wide variety of multi-processor systems including MPPs, SMPs and any type of single-chip multiprocessor, we concentrate on Network Processors, where most of the existing architectures use the multiple core design methodology. T...

Signal Modality Characterisation Using Collaborative Adaptive Filters

A method for extracting information (or knowledge) about the nature of a signal is presented, this is achieved by tracking the dynamics of the mixing parameter within a hybrid filter rather than the actual filter performance. Implementations of the hybrid filter for tracking the nonlinearity and the sparsity of a signal are illustrated and simulations on benchmark synthetic data in a prediction...
